The modern pentathlon is an Olympic sport that comprises five different events; fencing (one-touch ), freestyle swimming (200 m), equestrian show jumping (15 jumps), and a final combined event of pistol shooting and cross country running (3200 m). This last event is now referred to as the laser-run, since it alternates four legs of laser pistol shooting followed by an 800 m run (for 3200 m in total). The event is inspired by the traditional pentathlon held during the ancient Olympics; as the original events were patterned on the skills needed by an ideal Greek soldier of the era, the modern pentathlon is similarly patterned on events representing the skills needed by cavalry behind enemy lines.
