Rack
A horses jog, or trot, is a 2 beat gait.
American Saddlebreds are noted for a fifth gait called the rack.
Standardbred are not known for the gait called the rack and are not bred to do it. Generally Standardbreds trot or pace. Saddlebreds are a notable racking breed.
The step of a high-stepping horse is called a "trot." This gait is characterized by a two-beat diagonal movement pattern where the horse's front and hind legs on opposite sides move together. It is a common gait in many horse disciplines.
Your question is a little misleading because a rack is a different gait from what a horse running or galloping is doing. Fast racking horses can do the smooth rack gait at 25 to 30 MPH. For some neat videos search for "The Gravedigger" or "Rowdy Rawhide's Rocket" on you tube, or just speed racking horse.

walk, trot, canter, rack, and slow gait
The racking horse got its name from its smooth, four-beat ambling gait known as the "rack." This unique gait is comfortable for long-distance riding and was favored by riders who spent long hours in the saddle.
It depends on the breed and the gait the horse is performing. A Saddle bred or Walking horse performs several gaits in addition to the regular walk, trot and canter. These are called the slow-gait and the Rack. Paso Fino and Peruvian Paso horses perform the Paso, the Quarto, and the Largo as part of their gaits. These are laterally moving trot like gaits that are very smooth to ride. If you aren't being specific to the breed of horse you would simply call it high stepping. You may be thinking of the word "canter" which is often used by the untrained to describe a high stepping horse, but that word actually has a specific meaning that goes beyond high stepping. A canter being a specific type of 3 beat step with a speed between walking and gallop.
Walk - a four beat gait. The horse will be going at its slowest and when it lifts one foot the other three should be on the ground. Trot - a two beat gait. The horse will have two feet on and two feet off the ground. In a diagonal pattern. So if its front right is off the ground so is its back left. Canter - a three beat gait. The horse will be going slower then a gallop but faster then a trot. Gallop - a four beat gait. This gait is similar to the canter but it is much faster. You see Kentucky Derby races horses going at this pace.
