How to Calculate Cycling Power
What is Cycling Power?
Cycling power output (watts) determines training intensity zones. Power is more objective than heart rate because it responds instantly to effort — HR lags and is affected by heat, fatigue, and caffeine.
Formula
Step-by-Step Guide
- 1Power (W) = Force (N) × velocity (m/s)
- 2FTP (Functional Threshold Power): max power sustainable for ~1 hour
- 3Training zones are % of FTP
- 4Power-to-weight ratio (W/kg) determines climbing ability
