I've recently started using a treadmill for some of my runs due to weather and safety concerns. But I'm curious, do you guys view treadmill running as a valid way to train or just a last resort? Are there any benefits to running on a treadmill that I'm missing?
I've been forced to use a treadmill during the winter months and it's not my favorite. But, it's better than nothing. I think it's a necessary evil, but it can be useful for speed workouts and hill repeats. Just don't expect it to simulate the real thing. It's a different beast altogether.
