Gordon Ramsay finished the 2013 Ironman World Championship in Kona, Hawaii. The world's angriest chef swam 2.4 miles in the open ocean, biked 112 miles, then ran a full marathon, all in one day. He crossed the finish line in 14 hours and 4 minutes. And it was no stunt. He had already run 10 London Marathons in a row.
