What is Aquathlon?

Aquathlon is a multi-sport consisting of combinations of swimming and running. Races are continuous with no break between the two disciplines.

The official distances used at the ITU Aquathlon World Championships are 2.5km (run), 1km (swim), 2.5km (run). If water temperature is deemed to be too low, the distances are altered to 1km (swim), 5km (run).

There are a variety of race distances and combinations of swim/run and races can be held in pool or open water, and on road or trail.
