The Racking Horse is horse breed derived from the Tennessee Walking Horse, recognized by the USDA in 1978. It is known for a distinctive singlefoot gait. The breed has its own organization, the Racking Horse Breeders' Association of America, headquartered in Decatur, AL. Its goal is to preserve the breed in a natural state with little or no artificial devices that enhance gait. The horse's tail is naturally raised without nicking. Some classes allow special shoes that enhance action and a new class allows the use of chains, 6 ounces and under as action devices. The practice of soring, illegal under the Horse Protection Act, is also seen within the Racking horse world.
