Multisport race

Triathletes begin the swimming stage of the World Military Triathlon.

A multisport competition is a family of athletic competitions in which athletes race in a continuous series of stages or "legs", and rapidly switch from one athletic discipline to another in order to achieve the best overall time. Most multisport events are endurance races, consisting of aerobic activities such as cycling, running, kayaking and cross-country skiing.

Familiar events from the Olympic Games such as the pentathlon, heptathlon, octathlon, decathlon, and modern pentathlon are not usually considered to fall in this category, because their individual components are not held back-to-back.
