Tetrathlon competitions are comprised of four phases: the running phase, shooting phase, swimming phase, and the riding phase. A competitor’s combined scores in all four phases determines their overall placing in the competition.
The running phase challenges each competitor’s physical stamina and endurance over cross country terrain and may include negotiating obstacles such as hay bales, logs, and low fences.
The shooting phase tests a competitor’s skill and accuracy in a standing position, using an air pistol on a 10-meter course of fire. Any type of CO2 air pistol which does not exceed the specifications outlined in the Tetrathlon Rulebook is permitted.
The swimming phase allows competitors to demonstrate their swimming skills over a course length in meters or yards.
The riding phase of competition provides an opportunity for the rider and mount to demonstrate equestrian skills over a predefined, stadium jumping type course. Courses are designed as stadium, cross-country, or a combination of both, where the course incorporates stadium fixtures as well as natural terrain.
