I’m going to add my usual addition to the TR v Zwift… The tech required. I can do TR on my phone, on hybrid rollers, on my bike with a power meter.
I started dabbling with zwift at the start of lockdown. Casting my phone soon failed once I joined large events. So AppleTV purchased. I really don’t see using it on a non-smart trainer. And I haven’t since my Hammer has been out of action. I also ended up purchasing a new larger TV, as I was missing the edges on the very old 19 inch I’d happily used for netflix with TrainerRoad for years.
