Stadion or stade was an ancient running event, part of the Olympic Games and the other Panhellenic Games. It was one of the five major Pentathlon events. It was the premier event of the gymnikos agon (nude competition). From the years 776 to 724 BC, the stadion was the only event that took place at the Olympic Games and the victor gave his name to the entire four-year Olympiad. This allows scholars to know the names of nearly every ancient Olympic stadion winner.
