Some power estimates calculated with CPL models for World Tour time trial results.
More Details
Rider attributes (height, weight) are from ProCyclingStats.com
Aerodynamic drag estimates (rider CdA) use the anthropometric formulas set out in our
Aerodynamics Primer
Air density is assumed to be ISO normal for the event altitude. Wind speed is assumed to be zero.
Rider's power output is assumed to be the constant, average value which solves for their finish time.
Clearly these estimates will differ from metered power but offer similar accuracy to Strava's "Estimated Power".
Errors in CdA and estimated power tend to cancel, meaning the ratio Watts/CdA can be very accurate.
In experiments we have applied Watts/CdA estimates from past events to predict future times within seconds.
