A triathlon is a multiple-stage competition involving the completion of three continuous and sequential endurance disciplines. While many variations of the sport exist, triathlon, in its most popular form, involves swimming, cycling, and running in immediate succession over various distances.
The order of a traditional triathlon swim/bike/run is based on two things: safety issues and smooth transitions. All race organizers want to keep their participants safe. Triathlons are grueling tests of endurance, but they shouldn’t put anyone’s life at stake.
