Harness racing use a standing start. The sulky (informally known as a "bike") is a light, two-wheeled cart equipped with bicycle wheels. The driver (not a "jockey", as in thoroughbred racing) carries a light whip chiefly used to signal the horse by tapping and to make noise by striking the sulky shaft. There are strict rules as to how and how much the whip may be used; in some jurisdictions (like Norway), whips are forbidden. For exercising or training, the drivers use what is known as a "jog cart," which is a sulky that is heavier and bulkier than a racing unit.
Harness racing in Australia 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. Racing is administered by Harness Racing Australia (HRA) (formerly known as the Australian Harness Racing Council), with each State’s Principal Racing Authority agreeing to abide by, and to enforce the rules and regulations.
