I've spoken to medical professionals about this whole thing, I didn't mention specifics, just put it out as a theoretical situation. Much coffee was spat, many eyebrows were raised, I got the feeling that (even though they thought I was talking about modern day equipment / support), in their professional opinions, there was no way on this green earth, a human body could take that sort of punishment. Maybe to average 205 miles a day for a week, possibly for a month (although that could cause some pretty serious problems), but a year, they really couldn't see it. But as I said, if he did it, then that is pretty astonishing.
