Oh, and after a Zwift simulated ride yesterday, I decided that I wasn't really enamoured with that whole thing, either.
It, again, just doesn't feel quite right for me, on my trainer. Something about the inertia, or lack thereof, on the simulated terrain. Things like, if I'm going downhill and there's a little roller/bump, the change in resistance in the pedals is just too much and/or too abrupt - for me, that roughness around the edges takes it out of the realm of an immersive distraction and just makes it an obnoxious distraction, which isn't terribly fun.
Oh, and sprinting totally blows. For someone with snappy acceleration IRL and a power curve that skews to the short durations, it's a total wet blanket.
