Nonviolent sports consist of boxing, wrestling, track, and field. Nonviolent sports also include chariot races. Chariot races are a large attraction and are in the Roman Circus Maximus. Chariot teams receive names by color to help viewers decide whom they like best. All classes seem to be fond of the chariot races so be sure to join in on the fun here at the Circus Maximus.
