Managing your data into Final Surge is super important. This helps the coaches and you reconcile plan versus impact. It’s in this space that your fitness is created. You have to choose the right service to sync with Final Surge to get the data we need. You do that on this page in Final Surge:

Most importantly, know that you cannot sync all of the services as Final Surge will not reconcile. Instead, it will just show many workouts for the same activity. In general, we recommend that you sync Strava since it captures indoor and outdoor activities as well as power information. If you do not have Strava, you can sync Garmin, but it will miss your indoor workouts unless you manually add those through data into Final Surge. Here is a video.
