The Heraia were footraces held in honor of the goddess Hera in Olympia, Greece since early ancient times. The races were said to have been created by Hippodameia in gratitude for her marriage to Pelops.
Only virgins from Elis, Greece competed. They wore a short tunic that fell just above the knees. The right shoulder was bare to the breast. Competitors ran only about 160 meters in the stadium of Olympia. This was somewhat short of the stadium's complete length.
