An ultra-triathlon, as the name suggests, is a very long distance triathlon. The term ultra-triathlon refers to the three events that have a distance greater than the events of the ironman triathlon.

The three disciplines can be included in any order. In fact, they can even be in consecutive multiple individual triathlons held on consecutive days.The different ultra-triathlonsThere are several distances in ultra-triathlons.
