FAQ: Do you send % or Watts to Garmin?

There are two reasons we send watts rather than percent to Garmin. One is on your screen when training, most users prefer to see the target watts not the target%. Second, is that only new devices work with percent based workouts? Make sure you have your FTP set correctly in TrainerDay before sending your workouts to Garmin and you might want to periodically delete your workouts from Garmin and re-push as your FTP changes.
