The decathlon is a combined event in athletics consisting of 10 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.
A heptathlon is a track and field combined events contest made up of seven events. The name derives from the Greek ἑπτά and ἄθλος. A competitor in a heptathlon is referred to as a heptathlete.
