How long would it take you?
Your time up Mont Ventoux at a steady power, from a physics model.
Advanced: rolling resistance and drag
Estimate from a physics model (Martin et al. 1998), on the average gradient. Wind, surface, pacing and steep sections change the real time. More cycling tools
How this is calculated
P × 0.977 = ½ · ρ · CdA · v³ + v · m · g · (sin θ + Crr · cos θ), θ = arctan(average gradient), m = rider + bike, g = 9.81; solved for the speed v, time = length / v. Air density ρ: NASA GRC troposphere: T=15.04-0.00649*h; p=101.29*((T+273.1)/288.08)^5.256; rho=p/(0.2869*(T+273.1)); h = mean of start and summit altitude.
