Harness racing in Australia is conducted with Standardbred horses racing around a track while pulling a driver in a two-wheeled cart called a "sulky", "gig" or "bike". Standardbred racehorses compete in two gaits, pacing and trotting, and trotters may enter pacing events, but not vice versa. Pacers contest 80% to 90% of Australian harness races. Races are conducted in an anti-clockwise direction generally over distances from 1,609 metres (1 mile) to 2,650 metres, although some races such as the A G Hunter Cup are run over longer distances. Harness racing tracks typically measure from 700 to 1,000 metres.
