Garmin® has recently become aware of an issue where some workouts may not work correctly, such as missing or skipping steps. The issue can affect Garmin Coach plans, training plans and workouts made in the Garmin Connect™ app or Garmin Connect™ platform on the web, or workouts from other tools like TrainingPeaks.
While we work to resolve this, try one of the workarounds available.
Deleting the workout from the watch and re-sending the workout should resolve the issue. Follow the steps below on how to delete and re-send workouts to your watch.
Press START/STOP to access the Activity Menu.
