Triathlon, as the name suggests, is a multi-sport event consisting of three elements: swim, bike, run. The three sports are completed back to back without a rest.
The first triathlon was run on September 25 1974 by the San Diego Track Club, when athletes completed a 500m swim, a 8km cycle and a 10km run.
The sport got Olympic status in 1989 – the same year that the International Triathlon Union was formed, and the first World Championships were held over the Olympic distance – 1500m swim, 40km bike, and a 10km run. However, the triathlon was first run at the 2000 Olympic Games in Sydney, Australia, and it has been quickly growing in popularity ever since.
The triathlon distances vary, meaning there really is something for everyone looking to take on the fastest growing sport in Britain. The super sprint distance is the shortest, rising through sprint, to Olympic, and then middle distance and long distance.
