where do I find results of time trials which I do on routes automaticly in the same parts of rounds in free ride mode?
I assume you are asking about results for timed segments within a route (KOM, Sprint, etc)? If so they only show during the ride for a brief time after finishing that segment on the left side of the screen. If/when you ride it again it should show you your past 30 day results.
If you want to see it outside of Zwift you can sign up for Strava and sync your accounts then look under segments.
yes, I asked for timed segments within a route.
On Strava look for the segments with the title (Zwift Insider Verified).
