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.
Horse harness will not allow the horse to work efficiently. Putting harness on a horse is called "harnessing" or "harnessing up". Attaching the harness to the load is called "putting to" (British Isles) or "hitching" (North America). The order of putting on harness components varies by discipline, but when a horse collar is used, it is usually put on first. Throughout the ancient world, the 'throat-and-girth' harness was used for harnessing horses that pulled carts; this greatly limited a horse's ability to exert itself as it was constantly choked at the neck.
