A gaited horse is any horse that can naturally perform a smooth, four-beat intermediate gait instead of (or in addition to) the standard two-beat trot. These alternative gaits, known collectively as ambling gaits, keep at least one foot on the ground at nearly all times, eliminating the jarring bounce that comes with trotting. The result is a noticeably smoother ride, which is why gaited breeds have been prized for centuries as comfortable long-distance mounts.
How a Gaited Horse Moves Differently
Most horses have three natural gaits: the walk, the trot, and the canter or gallop. The trot is a two-beat diagonal gait, meaning the horse’s left hind and right front legs hit the ground together, then the right hind and left front. That synchronized landing creates a moment of suspension where all four hooves leave the ground, producing the up-and-down bounce riders feel in the saddle.
Gaited horses replace or supplement the trot with a four-beat gait that spaces the footfalls out individually rather than in pairs. The footfall sequence typically follows the same pattern as the walk (left hind, left front, right hind, right front) but at much greater speed. Because the beats are separated, there’s minimal or no suspension phase. The horse glides rather than bounces, and the rider sits almost motionless.
The specific four-beat gaits vary by breed and have different names:
- Running walk: The signature gait of the Tennessee Walking Horse. It follows the same footfall sequence as a regular walk but is faster and remarkably smooth, with the horse’s head nodding rhythmically.
- Rack (or single-foot): An even, four-beat lateral gait most associated with the American Saddlebred. Each hoof strikes the ground at equal intervals, and the speed can match a pace.
- Tölt: Performed by the Icelandic horse. The footfall pattern mirrors the rack, but the movement tends to be more fluid and expressive. Icelandic horses can tölt at speeds ranging from a slow walk to a fast canter.
- Fox trot: The Missouri Fox Trotter’s trademark gait. It’s a broken trot where the front foot lands just before the opposite hind foot, creating four uneven beats instead of two clean ones. This slight timing difference absorbs much of the impact.
- Paso gaits: The Paso Fino performs the paso fino (a collected, rapid four-beat gait covering almost no ground), the paso corto (moderate speed), and the paso largo (extended speed). The Peruvian Paso performs the paso llano, a smooth lateral gait with a distinctive rolling motion in the front legs called “termino.”
The Genetics Behind the Gait
For a long time, the ability to perform ambling gaits seemed to be something breeders selected for without understanding why it worked. That changed in 2012, when researchers identified a mutation in a gene called DMRT3 that plays a central role in coordinating limb movement. Horses with a specific premature stop codon in this gene have altered spinal cord circuitry that changes how their legs coordinate, making lateral and four-beat gaits possible while also inhibiting the normal transition from trot to gallop.
The DMRT3 gene is active in a group of neurons in the spinal cord responsible for left-right coordination and for synchronizing front and hind legs. In mice, knocking out this gene disrupted normal locomotion patterns entirely. In horses, the mutation doesn’t cause dysfunction. Instead, it’s permissive: it allows the horse to perform gaits that would otherwise be neurologically unavailable. Virtually all gaited breeds carry this mutation, and it appears to have been a key factor in the historical diversification of domestic horse breeds. Breeders didn’t know it at the time, but they were selecting for this single genetic variant across cultures and continents.
Common Gaited Breeds
There are more than two dozen recognized gaited breeds worldwide. Some of the most well-known include:
- Tennessee Walking Horse: Known for the running walk. One of the most popular gaited breeds in North America.
- Missouri Fox Trotter: Performs the fox trot, historically used as a ranch and trail horse in the Ozarks.
- American Saddlebred: A five-gaited breed that performs the rack and slow gait in addition to the walk, trot, and canter.
- Icelandic horse: A small, sturdy breed that performs both the tölt and the flying pace, making it one of the few breeds with five gaits.
- Paso Fino: A Latin American breed with a naturally collected, rapid four-beat gait.
- Peruvian Paso: Related to the Paso Fino but distinct, performing the paso llano with its characteristic front-leg arc.
- Rocky Mountain Horse: A Kentucky breed with a natural single-foot gait, popular for trail riding.
- Racking Horse: Closely related to the Tennessee Walking Horse, bred specifically for a smooth, fast rack.
Less commonly known gaited breeds include the Mangalarga Marchador from Brazil, the Marwari from India, the Florida Cracker Horse, and the Spotted Saddle Horse. The Narragansett Pacer, one of the earliest American gaited breeds, is now extinct but contributed genetics to several breeds still around today.
Why Riders Choose Gaited Horses
The primary appeal is comfort. A trotting horse transmits significant vertical force to the rider’s spine, hips, and knees with every stride. Gaited horses dramatically reduce this impact because their smooth footfall pattern eliminates the suspension phase. For riders with back pain, arthritis, or other joint issues, this can be the difference between being able to ride and not.
Research on equine-assisted therapy has shown that a horse’s walking gait mimics the human gait pattern, producing consistent, cyclical, rhythmical, and multi-dimensional movement in the rider’s pelvis. This movement follows a sinusoidal wave pattern that provides the rider’s neuromuscular system with repeated opportunities to practice postural control. While most of this research focuses on the walk, the principle applies to gaited horses at higher speeds: their smooth motion transmits a more predictable, less jarring pattern than a trot, which is why gaited breeds are commonly chosen for therapeutic riding programs and for older riders returning to the saddle.
Trail riders also favor gaited horses because they can cover ground quickly at their intermediate gaits without tiring the rider. A Tennessee Walking Horse in a running walk moves at roughly 6 to 8 miles per hour, comparable to a trot, but the rider can sit relaxed in the saddle for hours.
Saddle and Hoof Care Differences
Gaited horses do have some unique equipment needs. Their shoulder mechanics differ from stock-type breeds like Quarter Horses. A gaited horse typically needs a narrower shoulder spread in the saddle, around 12 inches compared to the 13 inches common for a Quarter Horse. Gaited saddle trees are also 1 to 3 inches shorter in the bar length to avoid interfering with the horse’s hip movement during its ambling gait. Putting a standard stock saddle on a gaited horse often causes it to pinch at the top of the withers because there’s no support at the shoulder, and the added weight of the rider concentrates pressure in the wrong places.
Hoof care, on the other hand, is less exotic than many people assume. The weighted shoes, stacked pads, and chains sometimes seen in the show ring are performance modifications, not standard care. In everyday farrier practice, gaited horses follow the same basic principles of anatomy and biomechanics as any other breed. A properly trimmed and balanced hoof supports the gait without special intervention.
The Soring Controversy
Gaited horse breeds, particularly the Tennessee Walking Horse, have been at the center of a long-running animal welfare issue known as soring. Soring involves deliberately causing pain to a horse’s front legs or hooves to produce an exaggerated, high-stepping gait prized in some show rings. Methods include applying chemical irritants like mustard oil or diesel fuel to the legs, using overweight chains that strike irritated skin with each step, or trimming hooves down to expose sensitive tissue.
The practice was widespread enough that the U.S. Congress passed the Horse Protection Act in 1970, making it illegal to show, sell, exhibit, or transport a sored horse. The law gave the USDA authority to create and enforce regulations aimed at eliminating soring and promoting fair competition. Despite more than five decades of federal law, enforcement has remained a challenge, and the practice persists in certain segments of the show industry. It’s worth noting that soring is entirely separate from the natural gaits these horses are born with. A well-bred gaited horse performs its signature gait without any pain or artificial enhancement.
