Maybe I'm just a skeptic....

There are days when I feel like 12 mph is pretty fast on my bike!

Same here

I have never seen the show, and from what I've heard about it I never will. If they really do expect people who are starting in that kind of shape to put forth the kind of effort I've had described to me at the very beginning - that is just irresponsible and asking for someone to get injured just to get good ratings. I think it would also discourage someone at home from doing anything at all if they think they have to start at that level of effort.
