The 2011 Ironman World Championship was held on October 8, 2011, in Kailua-Kona, Hawaii and won by Craig Alexander of Australia and Chrissie Wellington of England.
It was the 35th such Ironman Triathlon World Championships, which has been held annually in Hawaii since 1978, with an additional race in 1982.
Alexander's overall time broke the previous course record by 12 seconds, which was set by Luc Van Lierde in 1996.
Entry into the race can also be obtained through a random allocation lottery or through the Ironman's charitable eBay auction.
Murphy Reinschreiber, managing director of the Asia Pacific region for WTC stated that "TSB simply failed to provide all of the documentation necessary for CTSA to process the sanction."
