Strava and Garmin introduced a great feature to combat bike theft: hiding the start and end points of each ride. If Zwift is now going to sync and update outdoor rides as well, this is a feature that absolutely must be included in the app, if you want this feature to succeed Cheers.
Zwift only shows your outdoor rides to you so I’m not aware of a way this could be exploited. When you tap on an outdoor ride in Zwift, it should take you directly to whichever service it was obtained from.
