The sacrifices were carried out on a large altar built from the ashes of animals sacrificed in previous years. The ancient Olympics did not keep records, but there were tales of great achievements. For example, Aegus is said to have run home to Argos, which was over 60 miles away in one day, which seems like an impossible task. Another example is that of Milo, who allegedly carried a bull to the arena where the Olympics were taking place, slaughtered it and ate the entire bull in one go.
