We all ride Zwift to improve our performance, but we’re not all road racers in real life.
How about allowing “stopovers” to allow restart of a longer journey the next day? We could “buy” bikepacking equipment, and test our climbing skills with full panniers (and perhaps extra water bottles). It would also allow slower endurance cyclists to enjoy the further reaches of Watopia by doing the longest routes in two or more stages. I’ve seen tents on the hillsides already, so we could also stop at campsites!
