Power Data Estimates for the climbing stages

[meat puppet]

Do we know what specifically accounts for the different distances and gradients? Difficult comparison otherwise.

Different starting locations for timing most likely?

Lauren Ten Dam averaged 352W over 51:08 minutes on final climb.

must be yesterday. and according to strava algorithm, not directly from the powermeter, no?

 

[the sceptic]

beating baby Quintana by 1 minute with 200 meters less doesnt seem that outrageous.

Perhaps they climbed from the other side?

Yep yesterdays still waiting for todays, I didn't check date or profile, I think it is from powermeter though as it has symbol next to it on leaderboard

Indeed. Though baby Quintana was a time trial

Edit : Sorry yesterdays climb

He said he thought that was wrong, that he was pushing more

 

[ciranda]

The Dauphine stage last year had rain and pretty awful weather all day.

Do you think that might have been due to the heat though? Perhaps it felt harder in the heat.

this is the stage in qn?

204km stage.

Their powermeters have been off the whole season.

It's the next stage. MTT.

ok.

if it is a MTT, then they would have been riding much fresher unlike today's stage where they have already ridden an HC climb.

I still think today's nibbles performance is suspicious.


worst thing is tht we will never know, esp after the new UCI policy of silently publishing the list of offenders in a small corner in web

because the organizers can't choose only one finish. the start from where i time is always the same>>after the bridge which comes after the round crossroad d902a-d86
last year it was a different start.
anyway i don't think vincenzo did more than 6.2-6.3 w/kg.

 

[Merckx index]

6.12 watts/kg by VAM, for 33 min. vs. 5.84 yesterday for 50 mins. At least we can say the two performances are very consistent with each other. Whatever suspicion level you want to attach, pretty much equal. Unless wind, other weather conditions were drastically different on the two climbs.

 

[Trond Vidar]

Laurens Ten Dam is uploading to Strava using his Pioneer powermeter. Pretty cool stuff. It is not automated strava-power.

He averaged 374watts today on the climb to Risoul

He's listed in wiki as 67 kg. If that is correct, we have a massive discrepancy with VAM, about 5.6 watts/kg vs. 6.1. Suggests a strong tailwind.

Suggests his powermeter is total garbage. Like most Belkin powermeters during the whole season.

 

[nomapnocompass]

Exactly, the powerdata is wrong. Look at the weather forecast for yesterday re: wind

204km stage.

It looks like they did it twice. One in one stage and the other one in TT. I assume the fast time was done in the TT:

According https://twitter.com/chronoswatts/status/490463330998685696/photo/1
4 different finish lines :

 

[Netserk]

The start is also different. In Dauphiné last year they came in to Risoul (the city at the early part of the climb) from North-West whereas the other times (yester, Dauphiné '10 and l'Avenir) they came from North.

There was a light tailwind, 3 mph n/nw, which is normal for that area. Morning is a headwind but shifts to NW in afternoon......also those powermeters suck.

Speaking of powermeters sucking how is it SKY uses Stages? I have heard nothing good about those things

At a guess they are being paid $$$ to use them.

Marginal bank account gains >>> marginal performance gains via accurate power measurements, clearly.

We wouldn't understand power meters anyway.

FYI Stages is not a bad PM. I have been using PowerTap for about 8 years and just got a Stages on an Ultegra 6800 crank arm for one of my road bikes a month ago. It is solid and reads consistently though not quite as accurate or as responsive as PowerTap. Mainly, I find the Stages to read a little bit low at effort levels zone 3 (tempo aerobic) and below, but for everything above high zone 3 it is pretty darn accurate. So given the light weight and ability to use whatever wheels you want, I am happy with it.
