Stadion or stade () was an ancient running event and also the facility in which it took place, as part of Panhellenic Games including the Ancient Olympic Games. The event was one of the five major Pentathlon events and the premier event of the gymnikos agon (γυμνικὸς ἀγών "nude competition").
From the years 776 to 724 BC, the stadion was the only event at the Olympic Games. The victor (the first of whom was Coroebus of Elis) gave his name to the entire four-year Olympiad, allowing modern knowledge of nearly all of them. The race began with a trumpet blow, with officials (the ἀγωνοθέται agonothetai) at the start to make sure there were no false starts. There were also officials at the end to decide on a winner and to make sure no one had cheated. If the officials decided there was a tie, the race would be re-run. Runners started the race from a standing position, probably with their arms stretched out in front of them, instead of starting in a crouch like modern runners.
