I'm with M/P on this one--I'd rather take a beating than ride a trainer. Haven't ridden one in thirty years or so, and didn't enjoy it then. But I've heard folks say similar things about Zwift (whatever that is).Couldn't get away to ride yesterday so hopped on the trainer last night for a little over an hour and 23.4 miles with 144 avg heart rate. The group rides on Zwift are actually quite motivating.
