The ITU Aquathlon World Championships have been held annually since 1998, typically a few days preceding and in the same location as the ITU Triathlon World Championships, however since 2007 the championships have been held as totally separate events in different locations. The championships involve a continuous swim-run, typically with run being 5 km and the swim being between 750m and 1 km (however the distances have varied during the event's history). The championships are organised by the International Triathlon Union.
