The decathlon is a combined event in athletics consisting of ten track and field events. The word "decathlon" was formed, in analogy to the word "pentathlon", from Greek δέκα and ἄθλος. Events are held over two consecutive days and the winners are determined by the combined performance in all. Performance is judged on a points system in each event, not by the position achieved. The decathlon is contested mainly by male athletes, while female athletes typically compete in the heptathlon.
The modern pentathlon is an Olympic sport that comprises five different events; fencing, freestyle swimming (200 m), equestrian show jumping, 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. The event is inspired by the traditional pentathlon held during the ancient Olympics.
