How to use Cycling Power Zones Calculator (FTP)
Choose what you know (FTP, best 20 minutes or best ramp-test minute), enter the power and optionally your weight and threshold heart rate.
How it works
FTP ≈ 95 % of 20-minute power or 75 % of the best ramp minute. Zones follow Coggan’s percentages of FTP.
Example
An FTP of 250 W at 72 kg is 3.47 W/kg, with the threshold zone at 228–263 W.
