The sport of Ironman was developed in 1964 in Australia by Valentine Trainor to combine the four main disciplines of surf lifesaving into a single race; swimming, board paddling, ski paddling and running. The sport should not be confused with Ironman triathlon. It is typically run as a single event as a part of a surf life saving carnival, although it can be run as a sport in its own right. Internationally it is sometimes called Oceanman.
