According to Miller, the race consisted of 12 laps around a hippodrome, or horse track, and then 12 times in the opposite direction. The actual length varied depending upon where the event was held. Chariot racing was an expensive sport to compete in, and the owners of the horses and chariots—who watched as drivers competed in their name—used the event to flaunt their wealth. Hippodromes didn’t have a divider in the center of the oval, head-on crashes between chariots and horse teams sometimes occurred, which made chariot racing an extremely dangerous sport.
