I have never done Sufferfest videos, but I have 15 Spinervals DVDs. The videos are recovery workouts, technique, power, hill climbing, etc.. I have one that has you get off the bike and do core work and another one that you do weight work in between bicycling sets. Some people don't like Coach Troy; some don't like his music. I have my own music blaring, so that doesn't matter to me. I started buying videos around 2003, and I think he was the only game going then. I have used them to train for double centuries and triathlons.

Honestly, it probably doesn't matter which ones you choose, so long as you do whatever you get.
