Ironman World Championship course record holder Chrissie Wellington has announced that she will retire from competition. Wellington, who had taken off the 2012 season, said Monday that she would like to go out on the 2011 Hawaii Ironman, where she managed to overcome several injuries to compete in the race. “As an athlete I sought ‘the perfect race,’” Wellington said. “That race within myself where I dug to the depths mentally and physically, and that hard-fought race with my competitors. The World Ironman Championships in 2011 was the icing on the cake for me as an athlete. It was my ‘perfect race’ and it ‘completed’ me.” The 35-year-old athlete is a four-time Ironman World Champion and undefeated in the Ironman distance.
