From alternative workout to Olympic discipline
Triathlon was invented in the early 1970s by the San Diego Track Club, as an alternative workout to the rigours of track training. The club's first event consisted of a 10km run, an 8km cycle and a 500m swim. Over the next decade, triathlon’s popularity continued to build, and it soon gained worldwide recognition. Triathlon made its Olympic full medal debut at the 2000 Sydney Games. This helped the sport to become even more popular. It now has over 120 affiliated national federations around the world.
