The Racking Horse is an American gaited breed derived from Tennessee Walking Horse ancestry, recognized by the United States Department of Agriculture as a distinct breed in 1971. The name refers to the breed's signature gait, the rack, a four-beat lateral movement also called the single-foot because only one foot strikes the ground at a time. This natural gait distinguishes Racking Horses from breeds where similar movement requires artificial training.
The Racking Horse Breeders' Association of America (RHBAA), headquartered in Decatur, Alabama, serves as the official breed registry. Founded in April 1971 by a group of Alabama horsemen led by Joe D. Bright, the RHBAA was established to promote gaited horses shown without the artificial devices and extreme action seen in some Tennessee Walking Horse showing. The organization was recognized by the USDA in May 1971, establishing the official registry.
In 1975, the Alabama Legislature designated the Racking Horse as the official state horse of Alabama through Act No. 1153, recognizing the breed's importance to the state's equine heritage and economy. This honor highlighted the breed's significance to Alabama, where the RHBAA is headquartered and major competitions are held.
Over 81,000 horses have been registered with the RHBAA since its founding. The registry accepts horses demonstrating the proper natural racking gait regardless of ancestry, though most registered animals trace to Tennessee Walking Horse bloodlines. Horses from other gaited breeds may qualify if they demonstrate correct gait during RHBAA commissioner evaluation. The registry has reopened to new registrations from related breeds to combat inbreeding concerns that developed as the breed's popularity fluctuated.
