Power Data Estimates for the climbing stages

[Dr.Guess]

No. I am still speaking about Swedish commentators.
Also, vayers claiming on Twitter that 2005 time is 9:33 up to Mende.

vetoo confirmed my time. i take seriously my hobbies.

 

[roundabout]

I checked the youtube video of that stage today and it confirmed my recollection that the start of the climb by the main group was missed by the coverage.

Makes me wonder how the climb was timed.

2005:3,1 km@10,0%---9:12---average speed 20.22 km/h(Armstrong-Basso-Ullrich-Evans)

Must have been very cleans

2005-2008 evans would be climbing far better than Quintana today and even Froome would have a hard time dislodging him imo

Still slightly worrying they lost over 10 seconds to the clean Miguel

Evans climbed Plateau de Beille in 2007 30 seconds slower that Quintana and co this year.

that is simples

you take the 290 meters that were not filmed from the start. you watch the videos of all the other years and see in what time they did it. for example, the breakaway this year did in 51 seconds.
now CSC in 2005 went full throttle, they went around 14 seconds faster.

there is always a 5 second margin of error which i assume. i always said it.

you can check it yourself if you're not a belieber

 

[Red Rick]

Seems reasonable

 

[roundabout]

Yeah seems reasonable, except for the 14 seconds faster part. That would be 2+ minutes faster over the 3km at that rate Cummings probably did the climb in under 11 minutes.

Make that well under 11 minutes.

Edit 2: very roughly Cummings did the climb in about 10:30 at most this year. Pretty hard to believe that in a hypothetical race he would lose only 70 seconds in the last 2700 meters of the climb to the class of 2005.

 

[jens_attacks]

Cummings did 10:20

And this is a 10 minutes effort. Losing a minute is a lot, it's not alpe d'huez
The peloton always does the first ramps of a climb launched, at very high speed. It was the same in paris-nice
You definitely can't extrapolate like you did, saying that if you lost 14 seconds in 300 meters then you will lose 3 minutes in the whole climb. It is wrong, sorry.

 

[jens_attacks]

Also it has to be said that riders like cummings, pinot or bardet didn't work in the breakaway. They were fresh, protected from the wind almost like the big guys from the peloton.
Cummings time is not surprising ( that sounds awkward)

*clean evans

When comparing recent climbing rates to those of the EPO days people seem to assume it is impossible for a 'clean' rider to match the EPO times, but surely there has been gains in other ways in recent years. E.g. Prolonged altitude training camps (which is basically a legal expensive way of replicating the effects of EPO), better training techniques, better nutrition , facilities etc. also are the bikes lighter now or has the 6.8kg limit been in place for a long time?

Isnt that the point of altitude training? To increase red blood cell count

Quintana on La Toussuire:

Around 70% drafting. Assume some slight headwind:

5.58 Watts / Kg
5.66 Watts/ Kg (Ferrari's formula)

Re: Re:

Math model (Energy Equation).

Several web pages for that. I used my own in order to observe the range of possible outcomes.

 

[Dekker_Tifosi]

Gesink on La Toussiere was around 366 watts so Quintana's estimate is about right. Most of the climb was done in average pace and mostly drafting until 5kg to go

 

[Dr.Guess]

gessink rode like LeMond? (no baiting intended)

the weighted average is also insane. This stage was hard.

What range of outcomes do you get?
What assumptions are you using?

Cmon, still no exact Alpe d'Huez times for all the top 100? You guys disappoint me
