I always found that training for a century messed with my weight. It was too hard to eat to support all the riding without gaining weight. I would think something like PBP would be the same thing raised to the nth degree.

I'm in again for this challenge, since I was just starting to make progress toward my goal at the end of August, and now I'm all messed up with my vacation. I'll weigh in when I return to civilization in a couple of days. My goal is still 140.
