Time in power zones

Zones follow the 7-zone model used across TrainCraft, measured as a percentage of FTP.

  • Z1 Active recovery (up to 55% FTP)10 min · 11%

How the numbers are calculated

Duration is the sum of all blocks. Workout Score and Intensity Ratio are calculated from the interval targets with the same formula as the TrainCraft workout builder, where one steady hour at 100% FTP scores 100. Warm-up and cool-down blocks in this workout hold a single target, so they count at the percentage shown in the table.
