Pelops with his charioteer Myrtilos secretly replaced the bronze linchpins of the King's chariot with wax linchpins. During the race, the wax melted and Oinomaos was thrown from his chariot and died. Pelops and Hippodamia got married and Pelops celebrated his victory with the Olympic Games.
According to another myth, poet Pindar in his Olympian Ode tells the tale of how King Augeas of Elis reneged on his promise to reward Herakles for cleaning his stables. Herakles attacked and sacked Elis and started the Olympic Games in honour of his father Zeus.
