Upcoming workouts can only be managed in the platform in which they are generated. This means if a workout has imported from TrainingPeaks, Final Surge, or 2PEAK, the workout must be deleted or modified in the platform in which it originates. After modifying a workout, these changes will automatically sync to your Stryd calendar.
If the workout is prior to the current day, you must delete the workout from the Stryd mobile app or PowerCenter.
If you have additional questions about this, please contact us at firstname.lastname@example.org.
