I had read that it was possible to switch workout rides without quitting the app. Just click on the screen, then click menu, then click workouts, and click a new workout. Easy…
BUT!
The app will post the new workout under the name of the original workout to Strava. It was wrong, as I remember, in the activity list in the Zwift game app too. So sure I found a bug. Yeah, the bug was the idea that Zwift fixed the problem of switching workouts during a ride. That is STILL not possible.
Zwift support suggested I post this to get people aware that nothing has changed, and also to get more people to request Zwift programmers come up with a way to do this without quitting the app and re-invoking it, or risking a ride being posted as the wrong ride.
So ride on, but if you want to change a workout, remember to post that it still doesn’t work without quitting the app, and quit the app, and restart it and choose the workout you now want.
