Power Data Estimates for the climbing stages

[Don't be late Pedro]

Froome did post some of his Vuelta numbers though.

As if by magic...

What's the point. Power means nothing unless it's above Boardman's or something like that.

I like the line about Froome "now knowing his true potential".

 

[iZnoGouD]

he has quite a low heart rate at FTP -.-

What was it prior to working with Ferrari?

I don't know. My point was simply that the poster was wrong in claiming that Armstrong's VO2max wasn't as high as that of, e.g., Evans. Whether he had to dope or not to get there is a different question.

 

[MajorTom]

5.95 watt/kg average over 1 hour is probably what the most talented rider in the world could do clean and also rested. Over 15 minutes in a rested state maybe 6.3 w/kg.

That final climb yesterday was more of a 60 minute effort though than a 15 based on Levi's comments.

Power file says Brajkovic was riding at 355 watts on the final climb, he weighs about 63 kg. His normalized power for the whole race was 266 though, or 75% of threshold. Os it would not have been possible to really go harder than FTP at that point. I mean in all serousness, as a cat 1 rider myself; go out there and do a 4 hour tempo ride and try to ride at FTP for longer than 15 minutes. Its impssible.

Brajkovič weights 60kg. You can calcaulate this from his data. There was something wrong with SRM on that climb, cause there is no power for 1 minute if you look carefully. That is the reason relative power is 5.9 w/kg instead of 6.3 w/kg.

Looking at Froome's Vuelta TT: 147bpm average HR to achieve 400 watts! Wow, his stroke volume must be massive to move enough oxygen to support that kind of power.

What was it prior to working with Ferrari?

Someone here recently posted some numbers (With weight and VO2max among other things) measured on 4 (or 5) different occasions through the 90's. There his VO2max was around 80.

Tried to search for it, but I couldn't find it.

Looking at Froome's Vuelta TT: 147bpm average HR to achieve 400 watts! Wow, his stroke volume must be massive to move enough oxygen to support that kind of power.

Or else his whole-body a-vO2 difference increased to compensate for a reduction in cardiac outout, and/or he was directing more flow to his working muscles, and/or his efficiency was higher than usual.

I've often wondered about the mechanisms explaining the oft-observed increase in power:heart rate in the fatigued state...perhaps someday somebody will study this interesting phenomenon.

I got 6.2+ w/kg for Froome.

I got 6.2+ w/kg for Froome.

can u be more specific please

 

[roundabout]

I'll need to recheck certain things.

 

[halamala]

So, in terms of what that means for Wiggins and co at the front of the stage, it predicts about 6.4 to 6.5 W/kg. Over 16 minutes, that's not at all unreasonable. To give you some context, calculations of climbing power output in the Tour de France in the 1990s and 2000s often estimated that top riders maintained power outputs of 6.4 to 6.5W/kg on the Tour's HC climbs, most of which take over 40 minutes to climb. So in other words, there was an era where the best riders were maintaining similar power outputs to what we saw on Saturday, for three times the duration. Put differently, all those riders would probably have been a minute clear of this current generation on this climb...

Taaramae wrote in his blog that he averaged 375 watts in this TT )and added that he missed additional 30 watts from usual self).

Took their time didn't they...nice climb but they need to find a place to arrive closer than today the next time.

If you can read French, do read this by Antoine Vayer (with the calculations of Frédéric Portoleau). It's too long for translating, and full of metaphors about politics, hybrid sportscars, etc. Nonetheless, it's extremely interesting.
They're calculating Watts (on the 70+8 kg pattern), and have come to the conclusion that Wiggins did 465 W on the short climb during the time trial, Froome more than 465 on La Planche, while Wiggins and Evans averaged a little less. Same thing Sunday, when for a short while a bunch of 10 riders climbed insanely fast.
They're expecting figures around 430 W in actual mountains. They're calling that figure a heavenly miracle (and also tackle Armstrong's 450).

They also mention a couple of doping products I didn't have in mind (any more), such as TB 500. Google it.

Completely idiotic political references in that article, besides they got the time up the Planche des Belles Filles wrong, it was 16'16" not 16'23", not a big difference I know, but what other mistakes have they made?

I don't know other mistakes.

Pour se convaincre que la gauche, avec son moteur seulement thermique, avait éventuellement pris le pouvoir, sur le court col final de la Planche des Belles-Filles (5,9 km à 8,53 % de moyenne en dénivelée, avec un faible vent de 10 km/h), nous tablions sur un temps de 16'45 à 450 watts.

According to Vayer (and Porteleau) time was 16:45. It should be 16:16. Difference is 29 seconds.

 

[halamala]

EDIT: misunderstanding

 

[Bala Verde]

Ferrari calculated the following figures:

After the usual flat stages, as always stuffed with too many crashes and broken bones, the short climb of La Planche des Belles Filles (500m of ascent at 8.5%) already offered a certain selection, with Froome, Evans, Wiggins and Nibali expressing 1844 m/h, equal to 6.47w/kg.

He was also surprised to see the high cadence:

The Sky riders are pedaling uphill with very high cadences of pedaling (often over 100 RPM), which seem quite excessive in relation to the power outputs, around 420-440W: either these athletes are riding below their limit, or the asymmetrical chainrings used by most of them require higher cadences in order to get the best out of them.

Come on please. Very slow overall time, but I'd love to have some climb estimates so we can add a few facts to the discussion.
