According to the L.A. Times, Gneiting took nine hours, 48 minutes, and 52 seconds to complete the marathon, which is probably a Guinness world record. Via the Times:
“I did it, but it was hell,” Gneiting, 40, said, shortly after crossing the finish line in Santa Monica. “Pure hell.” Featured in a Times profile last week, Gneiting is a former national champion sumo wrestler with a 60-inch waist who weighed in just before the race at 400 pounds.
Gneiting completed the marathon by jogging and walking and said there were several times when he feared he wouldn't finish, particularly when his rain-soaked feet developed terrible blisters.
“My feet were on fire,” he said. “Twice, blisters popped and just about brought me to my knees…. But I kept going.”
By the way, this wasn't the first time Gneiting ran a marathon. In 2008, he took 11 hours, 48 minutes, and 16 seconds to complete the same Los Angeles route. So that means he beat his old time by two hours. That's a boss right there.
