9) Derek stood in the stadion, the place where ancient Greeks held athletic contests. He watched as the athletes prepared to run a race, which was also called the stadion. The stadion was one of the most important events of the ancient Olympics. The length of the race was one stade—about 200 yards—which was the distance from one end of the stadion to the other.
