For short rides 1/2-1 hour I use spinervals. For long steady distance rides from 1 1/2 hours plus, I will watch movie or something motivational like Iron Man broadcasts. Yesterday I rode 2 1/2 hours on the trainer by watching a movie that I'd never seen before and a fun boating video that I have. Plus I crank the surround sound also. My goal is to do a 5 hour trainer ride.
