Laser Run is a sub sport of Modern Pentathlon. Laser Run is an event that involves a run, shoot,run, and shoot. It is a world class sport but not an Olympic one. The legs are raced with continuous transitions like triathlon. The race length is usually 800 m run and shooting at 5 targets on each lap.

Originally invented to create opportunities for training the run and shoot parts of pentathlon in real race conditions, Laser Run has now developed into it's own sport expanding rapidly around the world with over 150 competitions a year.

The Laser Run World Championship is held annually in August. Approximately 500 athletes have competed at each edition of the championships, representing some 50 countries.
