I recently completed an Ironman and used my Fenix3 for the entire race as well as my Edge 810 for the bike segment. As the Edge data is more accurate I'd like to replace the F3's data in GC with that from the Edge for the bike segment only.
Strava was smart enough to throw the F3 cycling data away and only display the Edge data when the activities synced over (and interestingly enough got the run distance correct - it was wrong both on-device and in GC).
