A short-distance triathlon is anything that involves a swim of 0.2 to 0.6 miles, a bike portion of 5 to 18.6 miles and a run of 1 to 3.9 miles. Intermediate-distance triathlons consist of a 0.7- to 1.2-mile swim, an 18.7- to 31-mile bike ride and a 4- to 8-mile run. Long-distance triathlons have an athlete cover between 1.3 and 1.9 miles in the water, 31.1 to 62 miles on the bike and 8 to 18.6 miles running.
