The first triathlon reportedly took place in the USA in 1974. It was held on Mission Bay in San Diego with 46 participants on a weekday summer's evening. This triathlon started with a run, followed by the bike leg, and ended with a swim. This triathlon and the next 3 races were coordinated by enthusiasts Jack Johnstone and Don Shanahan. A few variations of the triathlon were trialled over the next few years with some races starting with the cycling, then swimming and then running.
One of the original participants in that first triathlon at Misson Bay, was later responsible for the creation of the Ironman endurance triathlon concept, which first took place in Hawaii in 1978, with 12 finishers (all male). It was that first Hawaiin Ironman race that created the rise of triathlon as a sport phenomena. In the 1980's the sport boomed, and Ironman
events gained worldwide media attention. Television broadcasts showing athletes pushing the boundaries of human endurance sparked further interest in this new multisport concept.
In 1989 the ITU, the international governing body for triathlon was formed with representation by 25 nations with the aim to see triathlon accepted as an Olympic sport. This was not realised for another 11 years, however in the meantime, the ITU created an international standard for triathlon, which is the 1.5k swim, 40k bike and 10k run called the Olympic Distance, but also a short course of half the distance which became known as the Sprint Distance.
Before reaching the Olympic arena, triathlon appeared at the 1994 Goodwill Games in St Petersburg, Russia, and in the 1995 Pan American Games, Argentina. And finally, the world saw triathlon as an Olympic medal sport at the 2000 Olympic Games in
Sydney Australia. So Australia played a very important role in the rise of today's triathlon profile as a major sport.
Today, the sport of triathlon is growing at a rapid pace. Triathlon
clubs abound in every major city of Australia, and right throughout the world thousands of races are held. It seems, we all just love a challenge!
