Horse gait

Horse gaits are the various ways in which a horse can move, either naturally or as a result of specialized training by humans.

Classification

Gaits are typically categorized into two groups: the "natural" gaits that most horses will use without special training, and the "ambling" gaits that are various smooth-riding four-beat footfall patterns that may appear naturally in some individuals, but which usually occur only in certain breeds. Special training is often required before a horse will perform an ambling gait in respond to a rider's command.

Another system of classification that applies to quadrupeds uses three categories: walking and ambling gaits, running or trotting gaits, and leaping gaits.

The British Horse Society Dressage Rules require competitors to perform four variations of the walk, six forms of the trot, five leaping gaits (all forms of the canter), halt, and rein back, but not the gallop. The British Horse Society Equitation examinations also require proficiency in the gallop as distinct from the canter.

Trot

The trot is a two-beat diagonal gait of the horse where the diagonal pairs of legs move forward at the same time with a moment of suspension between each beat. It has a wide variation in possible speeds, but averages about 8 miles per hour (13 km/h). A very slow trot is sometimes referred to as a jog. An extremely fast trot has no special name, but in harness racing, the trot of a Standardbred is faster than the gallop of the average non-racehorse, and has been clocked at over 30 miles per hour (48 km/h).

From the standpoint of the balance of the horse, the trot is a very stable gait and does not require the horse to make major balancing motions with its head and neck. Due to its many variations, the trot is a common gait that the horse is worked in for dressage.

Eadweard Muybridge was the first to prove, by photography, in 1872 that there is a "moment of suspension" or "unsupported transit" during the trot gait.

Types

Depending on the amount of engagement and collection of the horse, the trot can generally be classified as "working", "collected", or "extended". By the rhythm, one may distinguish a true, two-beat square trot when each diagonal pair of hoofs hits the ground at the same moment from a four-beat intermediate ambling gait, such as the fox trot or the "trocha" sometimes seen in the Paso Fino.
