The 2012 Ironman World Championship was a long distance triathlon competition held on October 13, 2012 in Kailua-Kona, Hawaii.
The championship won by Pete Jacobs of Australia and Leanda Cave of England.
It was the 36th such Ironman Triathlon World Championship, which has been held annually in Hawaii since 1978, with an additional race in 1982.
Entry into the championship race could also be obtained through a random allocation lottery or through the Ironman’s charitable eBay auction.
Prior champions receive an automatic entry for the Championship race for a period of five years after their last championship performance provided that they competed in at least one full-distance Ironman race during the qualifying year.
