the 100 metre dash

The stadium at the archaeological site of Olympia, Greece is located to the east of the sanctuary of Zeus. It was the location of many of the sporting events at the Ancient Olympic Games.
The stadium was a holy place for the ancient Greeks, as this is where sporting activities dedicated to Zeus were held. The stadium was originally located within the temenos, with spectators able to view races from the slopes of Mt. Kronos. It was gradually relocated east until it reached its present location in the early 5th century BC. The stadium is connected with the sanctuary by a vaulted stone passageway.
The track is 212.54 m (697.3 ft) long and 28.5 m (94 ft) wide and surrounded by grassy banks on all sides. All the seats were made of mud and on the southern slope there was a stone platform, the exedra, on which the Hellanodikai, the judges, would sit. Opposite this, on the north slope, was an altar to Demeter Chamyne. The stadium could hold 50,000 spectators.
