He ain't heavy, he's a runner!

Meet Kelly Gneiting of Arizona, a former 400-pound former sumo wrestling champ who now owns the Guinness World Record for "Heaviest Person to Complete a Marathon" after finishing the March 21st LA Marathon in 9 hours 48 minutes 52 seconds (beating several other runners half his size!)

According to Kelly, the challenge wasn't an east feat. He told the Los Angeles Times that by the 10th mile he had no idea where he was and became delirious:
"I was really struggling in the last five miles," he said, "but I said to myself, 'If I have to crawl, I will.'"
Kind of makes you want to get off your ass and go for a walk, doesn't it?
