Kelly Gneiting is a 40-year-old, 406-pound hospital statistician from Arizona with a five-foot waist. He is also a three-time American sumo wrestling champion who plans to be the heaviest person to ever run a marathon this Sunday. If Kelly can do it, the rest of you better cross "chafing" out as a list of acceptable excuses. He also boasts the confidence of a woman one-fourth his size. "I have high self-esteem and believe I can do anything." [Telegraph UK]
