Which accounts to sync together

I run TR and Zwift in parallel, and dual record on my Garmin head unit. That way TR and Garmin each get their own native inputs to drive Adaptive Training and Garmin’s algorithms. I setup Zwift to automatically push to Strava and Training Peaks. On the rare occasion I do a Zwift-only ride, I manually import that into TR.

I record just about everything else except indoor cycling on my Suunto watch, which also pushes to Strava. Because I do not dual record Zwift on my watch, there are no duplicates.

This is my real architecture. It’s overly complicated for sure and could be streamlined by having a watch and head unit from the same company, and maybe in other ways, too, but it works for me.
