Adcock Park records updated
An old fashioned story of drug cheating
Not good, certainly, and even in the amateur ranks it was common enough to know of this sort of thing. Drinks that were "special" and only for a given rider - laced with brandy or whatever alcohol they preferred, to be used prior to the sprint... although what effect that may have had is difficult to judge - maybe the effect was in their head? Or bananas with amphetamines for that lift you need, or think you need, just before a sprint or major climb. And the ever-present No-doze tabs. It can't have been just me hearing these stories, or watching riders throwing tantrums when they got the "wrong" banana... can it?

Cronulla capers - racing in the Shire
Now it was great to get live TV coverage - but as usual we had ill-timed ad breaks when riders went away, and when we came back to the action we got a long interview with a rugby league coach. Oh well.
Great, dominating ride by Kate Nicols to win the women's crit. As for the elite male racing, it was great to see Rabo's Brown win and Disco's White making impressive attacks... but it had a feel to it, somewhat akin to "off season" or "staged". Now it may have been absolutely legit, but firstly we saw McEwen go away in a break and then get caught (so the public got to see the road sprinter in action); followed by a successful break and a home-town win (just!) by the pro sprinter. Hmmm. Local boy Whitey was 3rd. Hmmm. Now I'm convinced the locals were indeed trying - no question about it (great rides by local crit specialists Jose Rodriguez and Peter McDonald, btw) - but the pros were taking it a bit easy, surely? I have seen similar local crit fields blown apart (and lapped) by just one pro on his "off season" break... but who would profit from seeing that under the gaze of the crowds and TV cameras? No-one one, really. The pros want to put on a show - that's their job - and don't want to crush the locals just for the sake of it. And that's exactly what we got. It was great to watch, anyway.

That crash in Surfers
Now it may have been a mechanical incident that brought Davis down, but it didn't look mechanical. And why didn't the chasers simply pass Davis and continue the chase? I can understand Davis taking a lap out and (in theory) rejoining the chase bunch, but what about Brown and co? I'm not sure what held them up (did they all fall, or have 'mechanicals'?) but by taking a lap out and they rejoining the breakaway that they had nearly caught seems a bit rich. 5m is still 5m guys. Now if it had been a club race we'd just get up and chase again. Or did I miss something?
Neil Stephens on an Aussie Pro team
Maybe not. Point is that someone got Neil on a bike, riding, then racing, then winning. You and I know that winning - or at least having a sniff - is enough motivation to train and train some more. Neil's never shirked training. For me it was gentle persistence by the then Randwick Botany club president (thanks Col) that finally got me racing. Sometimes it takes some nudging. Neil surely had a host of other, different factors that got him going and kept him going. And now he's 'putting back' into the sport. I'm not a great fan of nationalism, indeed it's high on my list of the cheap tricks and bread and circuses used by politicians and power brokers to distract us from thinking straight, but I can see the excitement that will surround any 'national' team entering the pro peleton, be it Kazahk or Aussie. Anything that gets what amounts to an alternative sport (an alternative to footy and cricket!)'out there' in public view is good. If not great.

Osteopenia and cycling
We recently completed a study comparing bone density of adult male cyclists to that of runners and triathletes. Our subjects were competitive at the regional level, ranging in age from 18-60 years. The cyclists, as a group, had lower bone density of the whole body, leg, and spine compared to the runners and triathletes. Additionally, a greater percentage had osteopenia, i.e., bone mineral density less than one standard deviation below the mean for young adult males. The two groups of athletes did not differ in age, body composition, training load or diet. My point is that low bone mineral density among cyclists is probably much more prevalent than we know.
This is not the only such study to report that cyclists as a group have a lower average bone density. Now the question is why? Firstly you'd imagine that higher-impact sports would naturally require and acquire higher bone densities - indeed you could probably guess that cyclists as a group would be one step above swimmers and well below runners on this 'impact' scale. Now I'm not sure this has been verified, but you'd certainly imagine specialist swimmers to be 'worse-off' in that respect. So why do we not read of swimmers and osteopenia? Perhaps we don't read the right reports? Or is there another factor at play here, perhaps something to do with which body types are attracted to each sport? Remember that a swimmer's mass is supported by water, so hydrodynamics and technique is probably a bigger factor than outright mass.
OK, so here's my theory: cycling actually selects for low-density bone mass. If you looked at cyclists as sub-groups I'm imagine you'd see some pretty low figures for climbers and much higher numbers for TTers and sprinters (but still less than runners). Of course any gym work would assist the sprinters keep the bone mass up, but that aside you'd expect power-to-weight ratios to select for skinny, low-bone-mass riders against the heavier guys. Why? Simply because mass that doesn't propel you forward drags you backward. So the bigger, heavier guy must lose weight in order to be competitive with the lightly framed guy or girl, or they will simply change sports. Look at cyclists in general. They aren't built like football players, are they?
So when it comes to testing cyclists as a group of course bike riders will have lower average bone mass - it's an advantage to them! Now it's also an advantage for runners, but moreso for road endurance runners. (Although the impact alone will keep that density level up rather than down.) When you mix it up with triathletes you get a range of specialities (swimmers, runners and cyclists, or combinations thereof) and thus body shapes that even out the ratios a bit. Whereas with cyclists, especially road cyclists, it comes down to low mass almost all the time. Or you just get dropped. It's not as though you can make up time on your swim or run leg, eh?
Conclusion? It's not one thing. Yes, it's a low-impact sport, so by all means do your cross-training and jumps and take calcium plus vitamin D. But don't imagine that cyclists will become heavily built, with denser bones. In fact lightly built people gravitate towards cycling because they have an advantage. We are stacking the sport with osteopenics - because they go faster! Or at least that's my (untested) theory. And I - a long-term cyclist - am osteopenic, too!

Ullrich back in training, Armstrong case dropped
Basso of course has been cleared and has no current charge to answer, but is out of CSC anyway, by mutual agreement. Again, no positive result but a seeming taint on his name. I think the Spanish case rested on the name of Basso's dog, didn't it? He may race with a non-ProTour team to avoid ... well to avoid complications. He again is emphatic about his innocence.
CN also reports that the Armstrong case has been dropped. That was the French case built on allegations made in the book LA Confidentiel, les secrets de Lance Armstrong, co-written by sportswriter David Walsh and former L'Equipe cycling writer Pierre Ballester. Insufficient evidence, apparently. The book sold well, though.
Pez reports that David Millar and his old Cofidis teammates are attending a French court with regard to the Cofidis doping scandal of a few years back. The judge has telegraphed that he considers the riders to be the victims as much as perpetrators. It's EPO related and hinges on a physio's evidence.
I could go on... and on. What to make of it? Well overall we have the seemingly 'factual' positives of Landis and Hamilton et al balanced against the implications of suggestions by various witnesses, in some cases backed up by documentation and other evidence of varying degrees of verifiability. Whilst we can (perhaps!) more easily accept the positive findings of labs - even when we can't understand why Landis (for example) would have used such an inappropriate substance - it's even harder to stomach these seemingly vague as yet untested allegations that have put riders and their careers on hold.
Let's not forget that Basso, Ullrich and all of the riders that remain tainted by the as yet unproven pre-Tour allegations have had their careers either put on hold or their earning power seriously diminished. I wouldn't like that to happen to me in my working life - it's unfair and inequitable for starters. The quicker it's resolved the better - but don't hold your breath.

DNA testing for cyclists - and other athletes
Why do it, anyway? Why attempt (they can say no and face the consequences, apparently) to get DNA samples from every pro rider? From where I sit the DNA samples constitute - firstly - a better way to label samples, so we get one step away from allegations of tampered-with samples, altered labels, switched samples and simple mistakes. Of course it's not foolproof but it's better than what we have (so goes the argument).
Secondly - assuming we get appropriate samples, ie including mitochondrial DNA - it gives us the opportunity to monitor the genetic performance enhancement that is bound to come - sooner rather than later.
This has got to be a step forward for fairness and correctness in process, surely? So why would an athlete say no?
- Firstly, privacy. It's their DNA after all and it remains a very personal 'invasion' in many minds. It's the map of your genetic heritage for starters. It's like handing over your passport, your tax files and the password to your email accounts plus your entire family tree. To a body you may not entirely trust. You don't do it at the drop of a hat, do you?
- Secondly, fear of another sort of 'labelling'. Criminals are asked for DNA samples, not the general public. So in some people's minds it is tantamount to saying that the althlete is already guilty - or very likely to be.
- Thirdly, mistrust of 'the system'. Arguably neither the UCI nor WADA have shown themselves to be on the side of professional cyclists. If your livelihood was at stake, would you blithely agree to whatever was asked? Given the doubts raised about false positive testing, unless and until such doubts are erased - and trust rebuilt - we are only adding another potential flaw to a flawed system. Worse, DNA 'confirmation' of a positive test, when in fact the DNA test may at best only 'prove' the existence of a certain DNA signature, may lend weight to what could in fact be a false positive. It looks and sounds very scientific, so it may persuade some to believe more readily of the "guilt" of those tested.
- Lastly - although I'm sure we'll think of more reasons with the passage of time - they (the athletes) may actually have something to hide.
So what could we do to assuage some fears and remove the doubts?
Perhaps we need to distance the DNA testing -if not all testing - from the UCI itself and place the responsibility of taking and securely keeping all DNA sampling with a new trusted 3rd party. Whatever form that body may take it can't be allied with the UCI, WADA or any of the labs that do the testing. It needs to be a neutral body and clearly seen to be be so.
We also need to do some effective communication, not just with the riders or athletes in other sports but with the community in general. And get the heat out of the situation. And build trust between all parties. Which may mean no more grandstanding by politicians or frenzied over-reaction by the press. It may also mean that protocols are religiously followed by all parties - with no "leaks", no shortcuts in the system that muddy the waters with unnecessary side issues of unfair treatment.
Hmmmm. Sounds like a tall order to me. Do we have the resolve to do it?

Drugs in cycling - Landis et al
So when I exceed the speed limit in my car - something I rarely do by the way as it raises the accident risk exponentially (and if you think otherwise you are not thinking it through) - I recognise that I am breaking a law and may be punished for my actions. Rule of law aside, it's also unfair to the community; to risk those around me by my self-motivated actions alone. And it's unfair to simply pass the drivers who are not speeding as it is the vehicular equivalent of 'queue-jumping'. Why would you think it's OK to queue-jump in a car? No matter how you look at it, it's cheating the system and putting everyone else down. You could take an economist's view and say that you are prepared to wear the marginal economic cost of the speeding ticket in order to achieve some competitive advantage, but only a small percentage of speeders are caught, so the marginal cost is inequitably applied. Which is to say it's an imperfect market and - alas - simply cheating again.
Similarly if we do take our chances and take performance enhancing drugs we are not just breaking the law but putting others in jeopardy (by modelling poor behaviour to young riders) and taking an unfair advantage over those who respect 'the law'. It becomes an ethical question. Do I behave ethically and fairly to all, or do I act alone to take an advantage over others?
None of which helps us decide any of the outstanding cases. If we are to have a controlled situation then we need to control every participant equally and fairly. It means taking blood and perhaps tissue samples from everyone and keeping them throughout our careers - amateur as well as pro. It may mean taking a DNA sample as a signature by which we can verify exactly whose sample we are testing. Indeed, given the possibilities of genetic performance manipulation a DNA sample will become essential in the near future. If we don't do that then we risk the current farce continuing - or escalating - despite what others may argue. Not just in cycling but in every sport. The alternative? Let the whole issue drop and change the rules to embrace the cheats.
More of my drug-related ramblings here. (Drug-related but not drug-induced, though.)

Felt F1C carbon bike review
So that's the background. Now here's a CN review of a bike I've seen and enjoyed looking at... the Felt F1C. It's carbon, all over. It's tempting, but in a more utilitarian way than the latest Looks or Orbeas. It's just a neat, fast, fairly traditional machine at a good price. I'd have one!

Drugs in sport - again
Meanwhile, I remember ex-Pro Jonathan Vaughters writing in (I think) ProCycling mag about 5 years ago, calculating LA's assault on L'Alpe D'Huez and expressing great surprise at the phenomenal power output required. More recently we have this exchange (reported again in Cyclingnews.com) between Jonathan and Frankie Andreu about rumoured drug abuse in Armstrong's team. It's all hearsay, all gossip, as Jonathan says several times to emphasise the point.
Fascinating, if a bit bleak and cheerless when you think about it.

I want one
From most expensive to cheapest, your power measurement options (as I understand them) are now:
- Power measured off the cranks (most expensive, and you are stuck with it on that bike unless you want to do some major component-swapping - but surely the most accurate way to do it)
- Or from the rear wheel with a hub-embedded accelerometer (slightly easier to swap from bike to bike)
- Or by measuring chain tension (using optical sensors), a bit fiddly but cheaper
- Or by calculating power from base data (speed, resistance, altitude, temperature and angle of climb)

Cervelo's video site
From their newsletter - check that out too:
The Tour may be over, but the new videos keep on pouring in at cervelo.tv. There are three new videos from the Deutschland Tour in the Team CSC section (and we really recommend Stage 6 if you want to see some tenacious climbing efforts by Jens Voigt, who will bend but won’t break). There are also some more videos in the Cycling 101 section, including clips about where Team CSC’s mechanics, soigneurs and team directors spend their time.
Aside from the regular clips on cervelo.tv, there are loads of new videos in the Ventoux.tv section as well. Dave Zabriskie, Levi Leipheimer, Carlos Sastre and Fränk Schleck attempt to draw their first bikes, the final DZ music video is up, and there is a new Testing music clip. And last (and probably also least), there is a clip of Team CSC’s team building coach B.S. Christiansen getting in trouble.

Rogers and T-Mobile on the charge
Good to see Mick Rogers attacking in style, taking his team leader to the
top of the GC of the Regio Tour (result via Cyclingnews):

Next up is a 23km TT. Should be interesting...
Another alternative to SRM
Fo power data freaks we have SRM (perhaps the ultimate bike accessory,
using force transducer-equipped cranks), PowerTap (using a
transducer-equipped re hub), Polar (least invasive, using optical sensing
of chain deflection) and now... Ergomo. It's optical, but it's inside the
BB! Check it out at http://www.cbike.com/ergomo_powertraining.htm
OK, you can also use 'manual' calculations based on effort over time, like
the HAC4 does. That's the cheapest, lightest and probably least accurate
way to do it.

Lance vs Jan - high spin or low spin?
In considering the causes of cramping, one possibility is fatigue brought about by too-high (ie harder to push) gearing. The authors of this article examined "patterns of leg muscle recruitment and co-activation, and the relationship between muscle recruitment and cadence, in highly trained cyclists". They tested at "individual preferred cadence, 57.5, 77.5 and 92.5 revs min" using (one hopes) carefully placed electrodes. Sounds cool as well. And the findings? Well the authors say that "muscle recruitment patterns varied from those previously reported, but there was little variation in muscle recruitment between these highly trained cyclists". Specifically the "tibialis posterior, peroneus longus and soleus were recruited in a single, short burst of activity during the downstroke" and that "the tibialis anterior and gastrocnemius lateralis were recruited in a biphasic and alternating manner". They found that "contrary to existing hypotheses, our results indicate little co-activation between the tibialis posterior and peroneus longus".
So far so good. Muscle recruitment is important from many angles, not simply as an academic pursuit but as an aid to understanding how it is we can generate the power that we do and applying that understanding in coaching athletes in optimal patterns of training. Such understanding would also help avoid injury as well as assist in faster healing after injury.
Anyway, the authors found that "peak EMG amplitude increased linearly with cadence and did not decrease at individual preferred cadence. There was little variation in patterns of muscle recruitment or co-activation with changes in cadence". I take this to mean that most elite cyclists use the same muscles and that varying cadence does not significantly change the pattern of recruitment. In other words you are still using the same muscles, irrespective of the tested cadences.

My view: For me this means that Lance Armstrong spinning at 110 revs/minute is probably using the same muscles as Jan Ullrich at 90 revs/minute. It's important to pin that down. Higher cadences do not necessarily mean a different arrangement of muscles doing the work.
Beyond that important point, there are neuromuscular factors involved as well as the lower per-rev power output at higher revs, so a comparison and conclusion Lance vs Jan isn't going to happen here. However I think it's interesting to note that seating position could affect the outcome. To me Jan looks cramped on the bike. Highly effective but a little less comfy than Lance. Perhaps (this is me postulating, not the authors above!) position will be a defining factor and possibly cadence is less important to the ultimate outcome than we have imagined. Any professional opinions on this out there?
Creatine Supplementation Reduces Muscle Inosine Monophosphate during Endurance Exercise in Humans
Firstly it has been shown in past studies that Creatine supplementation will attenuate increases in plasma ammonia and hypoxanthine during intense endurance exercise lasting 1 hour. So it seems reasonable to suggest that Creatine supplementation may indeed improve muscle energy balance during such exercise - it's worth testing.
The authors report that Creatine supplementation significantly increased muscle total Creatine, however no difference was seen between treatments after the first 45 min of exercise. They conclude that "raising muscle
total Creatine content before exercise appears to improve the ability of the muscle to maintain energy balance during intense aerobic exercise, but not during more moderate exercise intensities".

My take on this is that Creatine supplementation appears to work in maintaining a balance in the ATP cycle during the intense 1 hour efforts that have been tested. This sounds like an A or B grader may benefit in a 1 hour criterium, for example. They may have more energy freely available at the end of the race and secondly (my guess!) may recharge quicker afterwards. However there's no benefit below one hour or at moderate rather than intense efforts. As always, tread carefully if you try any supplementation - and seek a wide range of advice beforehand.
Cycling and cramping
Firstly, what is a cramp? OK, obviously they are strong, involuntary muscle contractions that commonly occur during or shortly after hard exercise, or when cold. Most cyclists - but not all - get them in the quads, hamstrings and calves (or like me, in the feet!). They can really hurt, really suddenly.
One theory of "cause" is that as a muscle fatigues, the brain sends more and more signals telling that muscle to contract to get the same strength of contraction, ie to get the desired result. The theory goes that when the muscle becomes utterly fatigued the brain sends a continuous contraction signal, which initiates a cramp. It could also be a protective mechanism. "I've reached my limit or I'm damaged", says the muscle, or the nervous system; and so it locks up so it can't be used. Great news if you are bike racing, eh, and the quads are calling it quits?
So, it's not good, but maybe we need to get 'em sometimes. But how do we avoid them?
Firstly, avoid muscle fatigue in the first place. Ask yourself, which muscles are prone to cramping? Can I shift the load more evenly?
Secondly, ask yourself when is it that you cramp? Is it toward the end of a long or hard ride, or only when racing? It may be that you have simply not trained adequately for the distance or the intensity of your riding. Some people cramp just before or during the sprint, for example. A 30km race is a lot more intense than a 30km training ride, so gradually up your training intensity. Upping the training distance may help push your limits as well. But make changes gradually, by increments, not in one huge leap!
You may cramp when pushing a big gear. Perhaps your cadence is too low? Try using lower gears to help get some spin back. Try not to drop below 85rpm. Whilst your endurance is measurably better at lower cadences the effort per rotation is greater. So strike a balance that offers easier pressure on the pedals by going for more spin.
Ask also if you are dehydrated, have depleted your electrolytes or have run out of energy. This is basic. Don't get dehydrated - you lose power and it may bring on cramps. And don't "bonk" (the cycling version of 'hitting the wall') or run out of energy. Keep eating carbohydrate rich foods during your rides. Your needs will vary with intensity and training, but 1-2 energy bars or satchels every 25km seems to be enough for my purposes. Certainly eat at the start of the ride, but not so much that you want to vomit when the racing starts! You are just topping up, not pigging out. Eat a main meal 2 hours before riding. This pattern of eating should also fix your electrolytes, but on a really hot day consider electrolyte-balanced sports drinks instead of water.
Other reputed causes of cramping include various medications and inappropriate supplementation. Regular stretching of muscles may reduce cramping (but for me that causes them!).
And of course avoid the cold or any position thats cuts off your circulation. Stretching cold muscles almost always brings on a cramp for me; as does sitting in chairs with high support under the knee. I think it cuts off or limits blood flow around the hamstring... add in a fatigued muscle and whammo! Good luck!2nd place for Henderson in NY

Aussie track sprint heroes
Honchar vs Gonchar explained
from Cyclingnews:
"One of the side-benefits of Gonchar's two stage wins and stint in the yellow jersey was that he got his name back. A typing error on his passport condemned him to being referred to as 'Honchar' for years. The fame that Tour success brings finally allowed him to set the record straight, "Yeah! In the last few years, people got used to calling me Honchar, especially in Italy, but that is not my name," he said."

It's simple but it's fascinating
Jens Voigt poised to win D-Tour
Remarkable win likely here with Voigt hanging tough in the mountains and blitzing 'em in the TT. He's on fire, post Le Tour. Cyclingnews reports: Stage 7 - August 8: Bad Säckingen ITT, 40 km 'Jensi' takes it all The winner of this year's Deutschland Tour is Jens Voigt, and if there was anyone doubting his capabilities, he proved today that he was untouchable.

Brown wins Stage 4 in Germany
What a relief! He's had his ups and downs, but he looks pretty happy about winning a stage of the Deutschland Tour. Renshaw was in the Top 5 and Zabel has taken the lead. Can he hold on over the mountains? You'd like to hope so, but with Vino one of many contenders just 48secs back, highly unlikely.
On Landis: It's hard to know who's clean, what with masking agents and autologous transfusions, and we have to trust the integrity of the sampling and testing procedure. So is it as robust as we'd like? Cyclingnews gives a rundown on the B sample result here:Christian Prudhomme, Director general of the Tour de France, said Landis is no longer considered champion of the 2006 event, but added: "Until he is found guilty or admits guilt, he will keep the yellow jersey. This is normal. You are not sanctioned before you are found guilty.

Other sports and doping
So you could buy any sort of body-building drug at that particular gym, in my experience. Presumably other gyms as well. I also "knew" about the occasional cyclist's drink bottle ("bidon") that (it was suggested) contained alcohol, to give some sort of kick up hills or before a sprint. Don't know how effective it was, but a few people seemed to like it and claimed to "know". Bikes of course are build to carry bidons as well as riders and musette bags, but what about other sports?
'No-Doze' was also big in the '80s for that caffeine kick, and coffee itself gained notoriety in sports where being "aware" and awake was important. Again in cycling there were "special" bananas to be eaten just before a race finish. Now these were reputedly spiked with amphetamines, but who knows the truth? No-one did a laboratory analysis on this sort of stuff at the time and it may have been riders just bragging. But very, very few people were drug tested pre or post race, even at elite State level back then, so anything could have happened. (And I have yet to see a club-level drug test, even now. Tell me if you've seen one!)
So I can imagine, and it is just imagination fueled by innuendo and availability (particularly via the Internet), that some bike racers are using performance enhancing agents to "get noticed"; firstly at club level (basically weekly racing thoughout the year) and probably at State level. They would effectively get away with it. Testing remains something done at higher levels of the sport, not below. Not often, anyway, in my experience, would they get caught. On the other hand I have never myself seen a culture of drug use in cycling at first hand, beyond caffeine and stories of what other riders did. I heard about but didn't see the evidence.
Nevertheless we quite possibly get riders started on this stuff early and then they either chicken out, or get smarter. Or dumber? If there's money involved there's temptation. Of course cycling is not as "wealthy" as some other sports.
So what happens in other sports?

Web resources - Roadcycling UK
Road Racing from scratch By RCUK "I could do that!" Almost invariably it's around the time of the three great tours that many occasional cyclists get so carried away by the unfolding drama, passion and competitive spirit of the Giro d'Italia,Tour de France and Spanish Vuelta that they picture themselves flying along in the midst of an illustrious bunch or riding with relative ease up steep mountain climbs with cheering crowds lining the road. At least that's what appears to be the case, even though you know that the apparent ease at which the riders are "flying" along at an average speed of 45k per hour is deceptive and the whole idea, in fact, may seem totally mad and completely and utterly out of my league - even more so as the prerequisite is incredibly hard training, unbelievable talent and a super-human physique. But cycling is all about sticking at it.

Landis stands accused of doping
Landis stands accused of doping - steroid abuse - following a failed test after the lone, brave attacking stage - and win - into Morzine. I hasten to add that it's all based on an A-sample at this stage and nothing is proven. Now, given that he has a serious hip condition I don't blame the guy for taking cortisol - an approved substance under the situation - or any reasonable dose of anything that gets him through the day; but at this level of performance and success you can't take any chances. Whether or not he did it deliberately we may never know - and the B-sample may yet prove negative - but even as an accidental side effect of medication, or drinking beer, or whatever - it's unacceptable. To try and clear it up post hoc and 'prove' that the steroid levels are 'natural' seems dubious at best. We will all be left asking 'why didn't this 'natural' level show up in other stages or at other times?'

Back to normal
This is an interesting quote: Lemond has certainly not hidden his feelings on Armstrong, and when asked who would win today between Landis, him and Armstrong, Lemond at first chuckled, "I am biased! I can't answer that, [laughs.]" But then Lemond got a little more serious. "Every race is different. The race changed dramatically this year. For me I am a strong anti-doping advocate. I think we are seeing a true Tour de France winner, someone who might have otherwise been cheated out of a win." From ESPN reported via Cyclingnews.
I've collected a few other Cyclingnews race reports that may interest you:

Stage 20 - Le Tour 2006 - the dust settles
Meanwhile the white was taken by Cunego - a newcomer with a bright future. And Pereiro kept his 2nd place intact whilst Kloden took 3rd. Floyd Landis may not return next year and question marks will surround Ullrich and Basso for sometime. It's been a strange tour without the dominant players - and losing Vinokourov as well meant even more instability. When Valverde was injured we all wondered if anyone would survive this tour. But they did and the excitement along the way was palpable.
Roll on the 2006 Vuelta!

Stage 19 - Le Tour 2006 - the TT decides
Floyd Landis (Phonak) is poised to take his first ever Tour de France win overall, after finishing third in the time trial between Le Creusot and Montceau-les-Mines. Serguei Gonchar (T-Mobile) was first and it was 41 seconds back to Andreas Kloden (T-Mobile). Maillot jaune Oscar Pereiro (Caisse d'Epargne) fought on but couldn't hold back the charging Landis, ultimately finishing a disappointing but otherwise unexpectedly great fourth on the day, 2m40s behind Gonchar and 1m29s behind Landis.
Barring the utterly amazing (who could deny the possibility though!) Landis is unbeatable at 59 seconds up on Pereiro and 1m29s on Kloden. CSC's Carlos Sastre is now in fourth, 3m13s behind Landis. If the cruise to Paris is as cruisy as usual Floyd will win. It is unlikely that the usual last day true will be broken, and intermediate and stage-winning points are insufficient to change the order. We've swapped one US winner for another!

Stage 18 - Le Tour 2006 - Status Quo
Looking at what could happen tomorrow in the TT is more interesting.
Oscar Pereiro (Spa) Caisse d'Epargne-Illes Balears leads Carlos Sastre (Spa) Team CSC by 12secs and Floyd Landis (USA) Phonak by 30s. Only if Floyd has a truly bad day, falls once and and punctures twice could he not expect to beat Pereiro and Sastre. Pereiro and Sastre instead will do their best - probably better than they have ever done, and limit losses. Since Landis was about 1m 40s quicker than Pereiro in the shorter TT in stage 7, let's assume at least that sort of result again, even though the longer distance probably favours Landis. Which would put Floyd in yellow, Pereiro 2nd.
Sastre, however, was 30seconds faster than Pereiro. So now we have Landis first, Sastre 2nd and Pereiro 3rd. However we must factor in Andreas Kloden (Ger) T-Mobile at 2m29s and Cadel Evans (Aus) Davitamon-Lotto at 3m08s on GC. Using our previous 'same time gap as for stage 7' assumption, Kloden would make up just 25 secs on Sastre and 54 secs on Pereiro. As the gap to Kloden is minutes, 2nd and 3rd is safe. Cadel was just 5secs behind Kloden in that TT so pretty much nothing changes their either. We thus have Landis 1st, Sastre 2nd, Pereiro 3rd, Kloden 4th and Evans 5th after tomorrow's (or today's now!) TT, if our assumption is correct.
The remainder of the top 10 are not a threat to the podium, but possibly threaten 4th and 5th place. Menchov is best placed to do that, but at 4m 14s back our assumption would rule out his success. He'll take 6th.
Of course it's the last roll of the dice, so all of this theory will come to nought. We have tired legs and a longer distance. We have a tougher course that may suit Evans over Kloden, for example. And may suit Kloden, Evans and Menchov over Sastre and Pereiro. Whilst it's unlikely, it's conceivable that 2nd and 3rd may be up for grabs to the freshest, fastest, hungriest TTer. And we could have punctures and crashes to contend with as well.
We shall soon find out.

Stage 16 - le Tour 2006 - Floyd falters
Cadel Evans and Oscar Pereiro hitched a ride with Kloden as he chased Sastre. Desssel kept his head and rode beyond expectations. It was another boilover on the GC. Pereiro takes yellow back and is looking strong. Kloden and Evans hauled themselves up the GC ladder. Spectacular. Wonderful. A stage of surprises, courage and sadly, a few casualties.

Stage 15 - Le Tour 2006 - Alpe d'Huez
So let's look at the top 18 or so on GC. Axel Merckx is 18th at 10min 25secs. He's a support rider doing his job for Floyd and Phonak. Floyd Landis (USA) Phonak is of course the leader overall and with his TT ability only has to match attacks from here to win the race. Oscar Pereiro (Spa) Caisse d'Epargne-Illes Balears has dropped one place to 10secs back and Cyril Dessel (Fra) AG2R-Prevoyance has hung on gamely to take 3rd on GC at 2.02 back. Pereiro is the better climber so he may put up a fight from here, hoping to stay on the podium or top 5 at worst. However Dessel whilst motivated and fighting hard will surely sink out of the top 10 over the next 2 or 3 days.
Denis Menchov (Rus) Rabobank is close behind Dessel and remains a true contender. He is close enough to attack but Landis probably has him covered. Carlos Sastre (Spa) Team CSC at 2.17 has proven he is close to his best in the climbs and has a good chance of top 5. Andreas Klöden (Ger) T-Mobile is at 2.29 and has finally demonstrated that he is a real contender - if only Stage 11 hadn't cost him such time! At 7th Cadel Evans (Aus) Davitamon-Lotto is 2m56s back and looking to reverse his fortunes over the next 2 stages and cement a Top 5 with a great TT. He is a real chance if he loses no more time and - hopefully - goes on the attack.
Michael Rogers (Aus) T-Mobile is way back at 5.01 and will ride support for Kloden. Still good for top 10 and may live up to expectations in the TT. The unfortunate Levi Leipheimer (USA) Gerolsteiner remains too far back at 6.18 - again, earlier losses continue to haunt him. All the usual comments apply... he should be in 3rd or 4th place, but isn't.
Thereafter we have Haimar Zubeldia (Spa) Euskaltel-Euskadi , Christophe Moreau (Fra) AG2R-Prevoyance, today's winner Frank Schleck (Lux) Team CSC , Yaroslav Popovych (Ukr) Discovery Channel, Juan Miguel Mercado (Spa) Agritubel , Marcus Fothen (Ger) Gerolsteiner, Michael Boogerd (Ned) Rabobank and Sylvain Chavanel (Fra) Cofidis at 9.56 to round out the 'sub-10-minute' riders. Many of these are support riders, others are hoping to rise further up the GC. Any of these riders have a show of making the action or getting a slice of it.
The next 2 mountain stages will tell the tale. And the 57km TT will be the final roll of the dice.

Rest Day 2 - Le Tour 2006
A have been asked to reflect upon the T-Mobile tactical 'blunder', and why the Italians always seem to falter at Le Tour, so I will!
Firstly, with regard to T-Mobile, they were probably too confident. They had multiple options to play, with so many guys up high in GC, so they attacked earlier rather than later thinking they could launch at least twice. Whereas Phonak only had one shot at it - Floyd - and couldn't attack early without risking losing everything. Same for Cadel. He has to be conservative and keep his powder dry until the last moment as he risks everything with any attack. I don't think we've yet seen the best of Cadel, or Sastre either. They missed the key final Leipheimer attack and couldn't - or perhaps decided not to - bury themselves and bridge the gap. Cadel knew he had time up his sleeve over all of these guys bar Landis, after all, so why waste the effort when a win was unlikely?
In hindsight it'd have been better for T-Mobile to wait - maybe - but then Menchov would've just saved his guys the trouble and hitched a ride on T-Mobile instead. Maybe Rasmussen, Menchov and company would've then won the stage with an attack in the last 2 kilometres, dropping a depleted T-Mobile in any case. At least T-Mobile took action and shed a few riders, making it clearer who was really in with a show. If they had waited maybe Mick Rogers wouldn't have lost so much time. But If Kloden hadn't cramped maybe he would've been up there anyway and we wouldn't be criticising their tactics at all?
I would've said the Giro was usually a better race with more attacking riding, but this Tour is shaping up as an exception. I don't really know why the Italians falter so spectactularly at Le Tour but have some ideas. (It seems hotter in July, for starters!) Pantani was an exception but so many of the Italians seem to have a problem that it's almost a national disease come July. In defence one could say that the Italians have already raced the Giro in May - it is their national tour after all - so they are probably depleted and less motivated, certainly less so than the French riders and les Anglos. Only the truly great riders back up and win both races, like Roche and Hinault. Armstrong didn't even try, which gives you a hint of the difficulty. Basso almost pulled it off last year, but few Italians take the tour as seriously as the Giro, especially when they are in Italian teams (which of course CSC isn't). Some riders who do well in Le Tour say that the Giro isn't as hard, that the competition in July is fiercer, but you rarely see 'em actually winning in May, either!
As well, this year's Tour has started on some seriously flat roads and has favoured the TT specialists especially, so the Italian mountain goats have had a tough time just getting to the mountain stages intact. Look how much time non-Italian Rasmussen has lost. It's rare to find a climber who can survive the flat sprinters stages and do well at TTs. Hincapie has trained for the climbs and made the same fall from grace. This year's race is made for the TTer who can climb as well - a rare breed. And once you've lost that much time in these long hot stages your motivation to get it back in the Alps may depend on how your team is feeling as well as how likely it is that you'll get enough time back to make up for what you've already lost. The Giro is more of a climbers race in that respect, with even the flat stages having significant hills. We may see the Italians having a crack at the Alps but it'll be for pride and a stage win. Most of 'em are now so far back that that's about the best we can hope for!
That's it from me!
