The article's title is a tad hyperbolic, but it is worth reading nonetheless.

About halfway down , it states the rules:

Every hour, you have to come to the start line and run a 4.16666... mile course (so 100 miles per 24 hours). When you finish, you can rest, eat, sleep etc. But on the hour you have to be back on the startline again. The winner is the one who is still there when everyone else has quit.

Yet another example of the weird and wonderful things that humans can, and do, do.
