It’s easy to put TR workouts on my Garmin Edge 520 if I decide to do a workout outside. Only takes a couple minutes to do this in Garmin Connect. For example I did Geiger+2 outside:
You need to tweak power zones in Garmin Connect to match TR, on mobile it’s located under More… Garmin Devices > Edge 520 > User Settings > Power Zones
The important items:
- set FTP to match TR
- set % FTP
Then whenever your FTP changes in TR, open Garmin Connect and change FTP value only, the zones will be set automatically.
