Triathlon has been an Olympic sport since its debut at the 2000 Summer Olympics in Sydney, Australia.[1] Its inclusion in the Summer Olympic Games program was the quickest of any sport:[2] the International Triathlon Union (ITU) was founded in 1989 and five years later, on 4 September 1994, triathlon's Olympic status was approved by the 103rd International Olympic Committee Session, in Paris.[3] The variant contested at the Olympics (called Olympic distance) is composed of a 1,500-meter (4,921 ft) swim, followed by a 40-kilometer (25 mi) bicycle race, and a final 10 km (6 mi) run leg. The distances were chosen based on the resulting format to be a challenge for participants (sprint triathletes as well as endurance competitors) and entertaining for spectators all over the world.[4]
