The stationary trainer is a strange beast. Hated by almost everyone and used by nearly as many, it allows for nothing but the vaguest feeling of actually riding your bike. In my opinion it’s WAY worse than running on a treadmill. Running sucks whether you are being chased by a gang of unruly thugs, doing a 5K, a marathon or on the treadmill at the gym… it just sucks. I respect and admire the folks who do it and enjoy it, but it sucks. When I do it, it hurts, it feels dumb and I ALWAYS think “this would be SO much better if I was on my bike.”
