The hippodrome at Mount Lykaion, located in a valley below and to the north of the altar, is the only extant hippodrome from Greek antiquity, and is therefore crucial to our understanding of Greek athletic festivals. The hippodrome was constructed on roughly a north-south orientation with a retaining wall of about 140 meters along the eastern side curving around the northern end. Modern excavations have discovered portions tapering column drums that may belonged to the turning posts at either end of the race-course, from whose location it appears that the hippodrome could have had a length of 320 meters and a width of 140. A bath building is being excavated about 35 meters to the northeast of the hippodrome; a large portion of it appears to have been dedicated to a cistern, and large stone basins from the middle of the structure have been uncovered
