A triathlon is an endurance sports event consisting of swimming, cycling and running over various distances.
The first known run/bike/swim triathlon was held at Mission Bay, San Diego, California on September 25, 1974. The race was conceived and directed by Jack Johnstone and Don Shanahan, members of the San Diego Track Club, and was sponsored by the track club. 46 brave participants entered this never-before held event. It is well-documented and was not based on the French events.
The International Triathlon Union (ITU) was founded in 1989 as the international governing body of the sport, with the chief goal being to put triathlon on the Olympic program. The ITU has never officially sanctioned the Ironman Triathlon. Some believe that the Hawaii Ironman should be recognized as the official world championship for the sport as a whole, and as such should be sanctioned by the ITU. For its part, however, the ITU has expressed little interest in supporting longer distance triathlons, choosing to retain its focus instead on the shorter races geared toward the Olympics.
