Triathlon fewer injuries than those who only use running as part of their exercise routine due to the incorporation of low impact swim and bike training. Triathletes spend many hours training for competitions, like other endurance event participants. There are three components that have been researched to improve endurance sports performance; aerobic capacity, lactate threshold, and economy. Injuries that are incurred from long hours of a single activity are not as common in triathlon as they are in single sport events. The cross-training effect that athletes achieve from training for one sport by doing a second activity applies to triathlon training.
Triathlon conditioning. Triathlon is considered by some to have its beginnings in 1920s France. According to triathlon historian and author Scott Tinley (and others), the origin of triathlon is attributed to a race during the 1920s–1930s that was called variously "Les trois sports", "La Course des Débrouillards", and "La course des Touche à Tout." This race is held every year in France near Joinville-le-Pont, in Meulan and Poissy. An earlier tri-sport event in 1902 featured running, cycling, and canoeing. There are documented tri-sport events featuring swimming, cycling, & running ( in that order) in 1920, 1921, 1945, and the 1960s. In
