You do know that you don’t have to do the ride in one go? Start a ride, pause, come back to it, even days later and it will carry on where you left off. Of course, you have to leave Zwift running on the device in between. I have an old computer running Zwift and I did The Four Horsemen over 3 sessions on successive days. Now I’m girding to try the Uber Pretzel. Cheating? Who cares. It even works if you start in a world other than Watopia which isn’t always available, your ride continues in the world you started in, just with fewer riders.
