Triathle is a sub-sport of modern pentathlon consisting of running, swimming and shooting.

Triathle is an event that involves cross country running, freestyle swimming, and laser pistol shooting in multiple sequences.

Triathle competitions are held under rules of the Union Internationale de Pentathlon Moderne (UIPM).

Compared to another sport under the governance of the UIPM: triathle is a laser-run with additional swimming.

It bears strong resemblance to triathlon (swimming, cycling and running) which is an endurance sport.
