I’d love to see a PR locker for each sprint, KOM climb, or lap on every route. For instance the two sprints from Achterbahn, as well as best lap time and KOM climbs in each direction would be available as a reference for you. It would be listed for each different route. Basically anything event that triggered a timer st the finish would have the PR recorded there.
The records would be available to you to refer back to beyond the current 30 days.
It would be nice to use to see how one’s Zwift train8ng was making them stronger in a certain area.
