(This article is about the track and field event. For other uses, see Decathlon (disambiguation).) The decathlon is a combined event in athletics consisting of ten track and field events. The word decathlon is of Greek origin, from δέκα (déka, meaning "ten") and ἄθλος (áthlos, or ἄθλον, áthlon, meaning "feat"). 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.
