Be sure to export your training to Garmin Connect and then follow these steps:
1. Open Garmin Connect
2. Tap "More" (...) at the bottom right
3. Select "Training & Planning"
4. Tap on "Workouts"
You should find your workouts there. If you still can't find your workouts, double-check that you have the correct Garmin account linked by reconnecting your Garmin connect account with JOIN.
