Workout files Sync to Garmin

Hi There! Is there a way to upload a workout to Garmin Connect so the workout’s Rx power and interval durations are displayed on my garmin 520? I see I can export .mrc, zwo and erg files but I can’t find a way to upload these files to Garmin. Thanks!

You can enable “Upload planned workouts” in the Garmin section in /settings and the next week or so of workouts on your calendar will be uploaded.

I need to add support for generating workouts in .fit format to support Garmin compatible download. That is on the todo list.
