OK, D-grade crits at the CCCC are short - 30mins plus a lap (another 2km, so about 16-17km). We start with the "D1" kids and drop 'em off after 2 or 3 laps, so we start slow, slow but then speed up. It was 32 degrees Celsius off the tar at 6pm - hot. And the wind was 30kmh from the NE. I was on the Felt F-50.
I dump my ibike data into a spreadsheet, so it comes out like this:
|MAX power ||1447W|
|AV (all) ||104W|
|AVERAGE (>0W) ||151W |
|TRIMMEAN (10%) ||88W|
The all-up average treats coasting as part of the race, hence Av (all) is just 104W but (Average (>0W) removes all zeroes... which is more 'real'. 151W still sounds low - but we did start slow!!
That's my own normalisation formula, by the way, and definitely a WIP. As a relative measure it gives me a way to judge between efforts. It emphasises the middle over the high-end of the power output range and tries to indicate real effort - all soft-pedalling or coasting is removed and we are looking at just the real "training" load, but I haven't yet perfected a way to recognise effort over time... so short rides are favoured over long ones. I'm working on it.
You can also see that there were only a few 600W+ efforts, and the 300 and 400W steps represent the once-per-lap climbs. Knowing all of this allows me to finetune my training to meet my race needs, although C-grade may well be more "attacking" and both the averages and the peaks will be higher (and more frequent in terms of peaks).
|10.5||Slope % (max)|
|-0.44||Slope % (average)|
The VAM is useless - not enough hills! But the 50.53kmh peak velocity in the sprint in useful. The 25kmh average is misleading as it covers 20km - warm-up, race and cool-down. The race itself averaged 32kmh (slow, I know, don't rub it in).
