So how much Watts (=Power) TDF Riders produce at the Tour ?
Here are 2 examples For climbing ability from Stage 9 TDF 2016.
I simply browse at Strava and tooked the Results. some riders Published their power data , and some only their climbing Time (Vam).
We can See that in the first climb of the stage: Alt de la Bonaigua (desde Viella rotonda Elurra) 22.1km 1,048m 5% .
– Thomas De Gendt finished the climb at :
357Watts climbing speed 1,280 meters for 1 hour at time of 49:06
Acording to “uncle” google his weight 68kg which means – 5.25 Watt/Kg

At the second climb – (Ordino-Arcalís 16.3km 913m 6% ) George Bennett
produse 287 Watts (weight 58kg) (1,236 meter per hour) time – 44:19:00

which means > 4.95 watt/Killo

acording to that Adam Yates (I only estimate his Power calculate that based on George Bennet Results) produce
5.18 watts/ KG

What can we learn from those numbers ?

Actually or probably That….

those are the Climbing Numbers During a Grand Tour. Why probably those numbers different actually from real Best Ability of the same riders ?

1. The graet Fatigh that those riders are after 8 privious stages.

2. Tactic – the climb was not a Time Trail which you need to give your all Best.

3. Drafting – yes – also during a climb (espeshelly 5-6%)

4. Tactic 2 – even the riders who climbed very fast, their goal was to “win” or to ride as fast as they need to win, and not to produse their real best.

So what is the real Best power of Those riders ?

we probably need to ask them. this is the best answer.

I think and estimate that most of the rider in the list are somewhere between 4.8-5.4 Watt/Kg for…. 3 Hours ?

Which means (if it’s right) That their is a big different between personal Best to best in Those Stages.

What Else ? more than that – mayby the riders didnt went Full gas at all at this climb ? (The puring rain did not help)

that’s it.

This is the all truth – Ruth.
(  BTW – i coppied The Numbers from Strava – i hope they are all correct – according to the Vam numbers – they  look allright)
