Two words -- challenging and sensational! I only have Local Hero, which is 85 minutes long and very very varied, and Revolver, 45 minutes long, and which alternates one-minute intervals of speed/inclines with steady pace intervals. There is no talking at all just the rock music, and really humorous written comments in huge block letters every few minutes. The exercise level youre supposed to be at is also displayed. You feel as if youre actually riding along the mountain roads, sometimes alone and other times with people cheering you on, and after doing these workouts a few times, I cant get myself to go back to my formerly beloved Spinervals with the indoor settings and sweating faces. I also love not having to insert dvds but just click on my iTouch and send it to Apple TV. Have you gone to the Sufferfest site and watched the excerpts? (And even the price is great.)
