Bike power zones from FTP
Enter your FTP (functional threshold power) in watts, from a 20-minute test x 0.95 or from an app. The calculator lists the seven Coggan zones in watts.
In short
Coggan zones are percentages of FTP: Z2 Endurance is 56 to 75 %, Z4 Threshold 91 to 105 %. With an FTP of 200 W, Z2 is 112 to 150 W. Zones describe effort levels only.
