Power Data Estimates for the climbing stages

[Alex Simmons/RST]

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.

Just half that tailwind speed would see W/kg overestimated by ~ 0.12-0.15 W/kg on a 7% grade. All of it would overestimate by ~0.25W/kg.

That's a level of wind that would be barely perceptible, smoke still rises vertically but drifts with the air. Flags barely move.

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

It's a sponsorship deal.

I suspect they still use their SRMs in training.

I have a Stages and while I have nothing to compare it to it seems great, consistent and easy to live with. I pedal and little numbers come up on my garmin. Incredible. Problem is the numbers are little....

#TDF, Stage 16. Port de Bales (11.65 km, 7.96 %, 927 m) Laurens Ten Dam: 33:27, 20.90 Kph, VAM 1663 m/h, 397 W [power meter]


= 5.9 W/kg. Bravo, @laurenstendam !!! #TDF

Massive tailwind, I guess. A shame no one has Pinot's time up the actual climb.

Ten Dam's power meter was 370W for the climb, for what it's worth.

Pinot - Avg: 382W

If it's tailwind 100% of the time, no?

Hardly going directly south the whole climb...

 

[hrotha]

I'd like to see Péraud's numbers from, say, the 2011 Tour de France, and how they compare to this year.

 

[roundabout]

So, what was the time today?

Fast or scary fast?

 

[whittashau]

I thought it seemed slow.

[Trond Vidar]

Pinot - Avg: 382W

Pinot does not upload his PM data to Strava. That data you see there is calculated by Strava.

Well, they were fairly fast

 

[roundabout]

That's a good time despite a much shorter and easier stage this year

It's amazing looking at the times before and after EPO

All within a whisker for 20 years, then WHAM a 4 minute improvement.

 

[luckyboy]

1993, 2001 and 2005 profiles

Hard to really quantify how much difference the length/toughness of a stage can make. Similar times to Hampsten and Millar in 93 with a 100km shorter stage.

 

[roundabout]

2005 stage was pathetically slow until Portillon or even Peyresourde. The break was nearly 20 minutes ahead at one point.

 

[jens_attacks]

today, first hour more than 50 kmph, week 3. high tempo on all the other climbs, i will post the times later on those. definitely impressive by papy peraud and nibali. the biggest performer i would say majka. i think we will have to go to sella 2008 to see a rider from the breakaway climbing at the same level as the big guns. \

tomorrow they should be all deads. or not majka to slaughter tourmalet record and win on hautacam losing a minute to peraud

 

[SirLes]

Andy Hampsten's time in 93 was seriously fast.
I thought the assumption was that he was dope free?

If he did indeed do that time dope free (or at least epo free) it makes it very difficult to draw conclusions based on climbing times.

mejia, hampsten and millar all on epo
pretty much all the guys who dropped fignon on telegraphe riding like motorbikes were on jetfuel.

Do you have Rominger's Galibier time from that year? Surely it must have been faster than Contador's, no? :O

Do we have any evidence for that? Serious question.

 

[Netserk]

Deductive reasoning.

 

[SeriousSam]

Depends on whether you believe we have evidence Big Mig was on EPO.

 

[SirLes]

Well, with regards Big Mig his doctor had history, Some of his comments have hinted at an admission of drug use and his body type was shall we say unusual for a climber.
Hampsten was always a natural climber, has been outspoken about drugs and I believe suggested that the increased use of epo hastened his retirement from the sport.

None of those things are conclusive of course.

 

[webvan]

Besides it's hard to believe the guy (Fignon) with one of the biggest contracts in the peloton wouldn't have known about or been approached about EPO...the story in his book makes little sense honestly.
