Too short (< 20 min)
HUMAN performance

More details about the "Power 78kg-standard" concept, the thresholds and the margin of error in the section watt the fuck ?

Please select a radar-climb :

The beginning of Risoul climb was a quite low slope (6%), ridden at 28km/h behind a AG2R team-mate. Consequently, the estimation cannot be done on this section (too much drafting).
The choosen section starts in Risoul, and ends at the finish line.
Majka's performance couldn't be measured on that section. But it was possible on a shorter section while he was alone (9.66 km, 25'42", 426W, 6.2W/kg), perfect analysis conditions.
For the full climb (from Guillestre), the times are (+/-5s) 31'50 for Nibali-Peraud, and 32'15 for Pinot, Bardet, Van Garderen and Majka

  No Watts on Ventoux climb, why ?

The power calculations are too imprecise because of the wind on top, that's why they're not published. But watts are published for the "forest" section ending at Le Chalet Reynard..
