This simulator will calculate a "power 78kg-standard" value, based on F. Portoleau's calculation method (©2013), and a performance threshold (© A. Vayer, the performance expert).
More details about these methods in the watt the fuck ? section.

 

Calculation parameters
Height (cm)
Cyclist weight (kg, dressed !)
Bike weight (kg)
Road condition
Wind (average, en km/h)
Exemple : No wind => 0. Low head wind => -1km/h. Strong head wind => -4km/h. Tail wind => 2km/h
Temperature (°C)
Posture on the bike
Aerodynamic equipment (aerobar, lenticular wheel, ...)
Drafting (%age)
Exemple : no drafting => 0. "usual" drafting => 2

  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..
