During the awards ceremony for a Hawai running race, a debate ensues among competitors about who is more fit -- swimmers, runners or other athletes. One of the participants, Navy Commander John Collins and his wife Judy, dream up a race to settle the argument. They propose combining three existing races together, to be completed in succession: the Waikiki Roughwater Swim (2.4 miles), the Around-Oahu Bike Race (112 miles, originally a two-day event) and the Honolulu Marathon (26.2 miles). "Whoever finishes first we’ll call the Ironman," said Collins. Fifteen men participate in the initial event held on February 18; 12 complete the race, led by the first Ironman, Gordon Haller. His winning time: 11 hours, 46 minutes and 58 seconds.
