I can't see sitting on that thing for hours simulating TDF courses or any other course when you are indoors and stationary watching tv. I'd rather use a cheaper trainer with my bike and get an intense workout in a 1/2 hour or an hour with a training dvd and be done with it. As said may times indoors is boring why drag it out and spend 1200 bucks or more to be bored? There are several outdoor workout options for the winter months that beat a trainer indoors.
