As runners, cyclists make good cyclists

But triathletes fare better. Well Armstrong was a triathlete many moons ago, and it shows. As a cyclist and not a runner I can quite honestly say that I was "fast enough", but only over about 400m max. After that it became a slog, a real slog.

Anyway, from CN: Seven times Tour de France champion and cancer survivor Lance Armstrong finished the 112th Boston Marathon in 2:50:58, placing 488th out of more than 25,000 Monday. Kenyan Robert Cheruiyot won the men's race in 2:07:46, missing the course record he set by just 32 seconds. He became the fourth man to win Boston four times, joining American great Bill Rogers.

Riders who also run

I'm not sure why, but plenty of riders are turning to running, especially after retirement from pro cycling. Is it a fear of incipient osteoporosis? The lure of a new challenge? Less time-consuming? Or is running just easier? (I doubt the latter.) Anyway, here are some more... starting with Rabo's Michael Boogerd:Meanwhile, he is still staying athletically involved. He plans to run the Rotterdam marathon on April 13, as preparation for the RopaRun, a three day event from Paris to Rotterdam which raises money for charity. "It is for a good cause, and now that I have stopped racing I still need do something to keep my condition on a good level," Boogerd said. "I now try to run an hour each day. It does me good. Later this year, I want to run the New York marathon." His training partner is Leontien Zijlaard-van Moorsel, who ran the New York marathon in 2007. "I asked him and Michael was enthusiastic," she said. "After my cycling career, I found running to be a new sport where I feel good. I think that running will also be good for Michael."

And Armstrong, of course: Lance Armstrong will continue his post-retirement marathon career by competing in the Boston Marathon on April 21, the race organisers announced Thursday. Armstrong qualified after finishing the New York City Marathon in 2007, bettering his previous year's effort with a finishing time of two hours 46 minutes and 43 seconds. The seven time Tour de France champion was well under the Boston Marathon's qualifying time for his 35-to-39 age group of three hours 15 minutes.
