The icosathlon, also called double decathlon, is an ultra combined events of track and field competition consisting of 20 events. The word "icosathlon" was formed, in analogy to the word "decathlon", from Greek εἴκοσι (eíkosi, meaning "twenty") and ἄθλος (áthlos, or ἄθλον, áthlon, meaning "contest" or “prize”).

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 icosathlon is contested mainly by male athletes, while female athletes mostly compete in the tetradecathlon. The event is overseen by the International Association for Ultra Multievents (IAUM), which also holds the tetradecathlon based on the women's heptathlon.

The men's world record for the standard icosathlon of 14,571 is held by Joseph Detmer of the United States.^[1] The women's world record of 11,653 is held by Lauren Kuntz from the United States.
