Perhaps off topic, why is there so much focus on zwift? I have been looking into a getting a trainer, but trainerroad seems much more appealing to me...
Horses for courses. Zwift is fun because it's interactive and, with a smart trainer, a person could almost feel like it was a real ride with terrain and elevation and everything.
Personally I prefer Trainerroad, because I have a dumb trainer and I got a lot more benefit last winter from using the structured workouts on Trainerroad than I did with Zwift. But -- a smart trainer would be useful with Trainerroad, too.
