Power-based training sessions from Stryd, TrainingPeaks, or Final Surge currently cannot be exported automatically to Polar or Suunto watches. You can therefore not automatically execute training sessions as you can with Garmin or Apple watch.

You can still use the training plans from Stryd, but will need to remember the power target and duration of each segment. We recommend using the lap button to mark each segment of the training so that your data lines up with your planned workout and the Stryd platform can associate your run with the planned workout.

If you are using a Polar or Suunto watch, you must disable automatic laps for the best possible experience as Stryd relies on the lap information to mark each segment of your training.
