Kelly Gneiting, a 400-pound former sumo wrestler, set a Guinness World Record as the heaviest man to complete a marathon. He finished the L.A. Marathon on Sunday according to the Los Angeles Times in 9 hours 48 minutes.

He weighed 396 pounds after the marathon, smashing the past world record of 275 pounds and beating his 2008 marathon time of 11:52.

"I'd like to see the Kenyan improve his marathon time by two hours," he joked.

Gneiting jogged the first eight miles and walked the final 18, saying afterward that he lost track of where he was after mile 10 because he felt delirious.
