The World Triathlon Aquathlon Championships is a aquathlon championship competition organised by World Triathlon.
The championships is a continually timed race containing a swim stage and either one or two run stages.
Typically, the race consists of run—swim—run segments.
When the water is less 22 degrees Celsius, a wetsuit is required and the race starts with the swim stage, followed by a single run stage, so that participants do not have to put on a wetsuit mid race.
However the distances have varied during the event's history depending on local circumstances.
