Import Average power from an activity in GARMIN

Here’s one way.

  1. Click on the day you did the workout.
  2. Ride
  3. Make sure the category is ‘Workout’ (for me that is default anyway)
  4. In a format like this (see workout builder for more) -1h5m 200w put in the duration and avg watts. This should populate the duration and load fields
  5. put the category to ‘Manual Activity’. It will keep the duration and load fields
  6. fill in the rest and hit OK

Hope that works for you
