I have met this man in person and yes.... he is certifyable. If you have any question at all, read his book "Ultramarathon Man: Confessions of a Night Runner" I think it's called. I was all inspired by the first few chapters until I got to the part where he got mad because they pulled him off of the course at Bad Water, when he was unconscious!!

He is kinda good looking though if you like men with only 3% body fat.
