JV1973 in 2009 said:Ok, so answer the 20 min effort vs 40+ minute effort question, I only have limited information from elite athletes, so this isn't a University study....
That said: CVV can produce about 5.9 watts per kg in peak form for 40+ minute climbs, Wiggo is a bit more at 6.1 w/kg for this length of effort.
From the pre-Tour tests both riders have done up Rocacorba (a 33 minute climb) I know that Wiggo was at 6.1w/kg and CVV was 5.7 w/kg (He was off form a bit in June). However, Wiggo did a local 10 mile TT in GB about 2 weeks before the Tour, or 5 days before the Rocacorba test. He posted a time of 18mins flat (and was disqualified for using a 1080 wheel...funny rules over there). Anyhow, his power was 482 watts, so using his Tour weight of 72 kgs, so 6.7 w/kg. So, anecdotally, there's about a 9% decrease in power when going from a 20 min effort to a 40+ min effort. At 6.7 w/kg you certainly can climb at a VAM of 1750, but at 6.1 you wont even hit 1700 (again, anecdotal based on experience).
The last TT in the Tour Wiggo averaged 434 watts, consistent with his previous tests of 40+ minutes and just about 6.1 w/kg. I dont have any data for Wiggo up climbs in the Tour, as he didnt use a PowerTap.

http://www.cyclingnews.com/news/wiggins-and-sky-surprised-at-stage-7-damageAsked if he was surprised that none of his rivals had attacked, Wiggins said: "I was little bit. I knew I was dictating the pace and that I wanted to keep it high threshold and not go too much into the red and I knew that if someone wanted to attack off that pace they’d have to be going quite a bit more, which I know is not really sustainable if we’re riding at 470 to 480 Watts. Someone is going to have to go a lot harder to sustain that. As long as we gauge it like that I knew we’d be alright."

Brajkovic - 351 Watt? Weird. Err, it's only 5.4 W/kg (according to Wikipedia he is 65 kg). And I have to correct my mistake. Wiggins' power output isn't 472.5 Watt. It's 465.3 Watt.Race Radio said:I don't get this. Jani was 351 for the final climb (17 min) how is Wiggins 472 when he was only 48 sec ahead of Jani? Even factoring marginal weight differences it seems like a huge difference. Also Wiggins sat on the entire climb while Jani rode mostly by himself. Not a huge difference at 22kmh but it does save a few watts

Race Radio said:We have exact numbers from Jani powerfile. I think he is around 63kg and Brad is @ 68. Brad also sat on. I can't see Brad much higher then 400.
thehog said:I'm useless with data but Jani B has posted his online:

Looks like they were smokin' thus everyone got dropped!
D-Queued said:510 Watts?
Finally, someone bested Indurain's 508 watts*
Must be improvements in training and nutrition.
Dave.
*Yes, that was over an hour. But, still, 510 watts from a stick figure?
zigmeister said:Based on the comments in the trainng peaks, and that some TT guys did 525 watts for 13-15 in the prologue, this is expected power.
Leipheimer said the run in was brutal and he almost felt completely tapped before the climb even started.
Then they just hammered it up that thing for 15 minutes with a nasty pace.
function said:There is no comparison, 500W for 4 minutes is a function of vo2max and not "muscle bulk"

Don't be late Pedro said:Is someone able to put these numbers into layman's terms? I understand the gist of what the numbers represent but have no idea what is considered 'normal' (read clean).
Cavalier said:In terms of VAM, the speed of Froome's climb exceeds everything ever done before in the tour with the exception of Contador climbing Verbier. It beats Pantani, Armstrong, Ullrich, and Indurain.
