The first documented Olympic Games took place in 776 B.C.. Many historians, however, believe that the Games had already been established for many years at that point. According to legend, the Olympic Games were founded by Heracles, the son of Zeus. There was only one event at the 776 B.C. Olympic Games -- the stade, a race of approximately 192 meters. The winner was Coroebus, a cook from Elis, making him the first documented Olympic champion in history.
