Wow. I read that report last night, and couldn't fall asleep thinking about it. I'm kind of embarrassed to admit that I don't have the kind of relationship with my body that I can get it to do anything even a little painful. Lucky for me, riding is never painful at the distances I ride . I think we all have our strengths, but overcoming the voice in my head that tells me "this sucks" is not mine. Maybe I wasn't as much like that when I was younger, but now, I definitely like things cushy.

But, I'm really curious. What makes you want to do this? Is it just the feeling of accomplishment at the end? I would need some huge reward a part of the goal, to have a chance of completing anything even a quarter as hard. Did you do that (give yourself something amazing)?
