This is a phenomenal site.
I'm sure it's been discussed on the other threads, but he was caught and DQd at the Delaware Marathon.http://races2run.blogspot.com/2010/08/world-record-runkip-litton.html
People that cheat in races like this are sociopaths. Every so often a new one pops up. One thing that I've noticed is that they tend to be doctors, for reasons I cannot explain. There was one discussed on Letsrun a few years ago, I think he was in his upper 60's.
Then, there was an infamous doctor and professor in the DC area that got DQd at 2 marathons for course cutting. I met him once and knew that something was seriously wrong with the guy. He could not stop talking about himself, both his running accomplishments and jumping out of airplanes in Rwanda while getting shot at.
It makes you wonder if these people cut corners in their medical practice as well.....
