(harness) or Road gait (roadster): Is slower than a working trot, but faster than a jog trot. This gait is one of the gaits used in harness classes at horse shows. Working trot or Trot: The stride length (note: some breeds have naturally varied strides) is "normal" for the horse and is the natural trot of the horse when under saddle. It is a gait between the collected trot and medium trot. Medium trot: A trot that is more engaged and rounder than the working trot with moderately extended strides and good, solid impulsion. The medium trot lies between the working and the extended trot. Park trot: Sometimes simply called a Trot in a given class and seen in saddle seat and fine harness classes for Saddlebreds, Arabians and Morgans. It is a showy, flashy trot with extreme elevation of the knees (forearm is horizontal or higher and the hind legs are extremely flexed). The head is held high and at times a horse may hollow its back and lose cadence in an attempt to achieve high action in front. The hindquarters must be engaged for it to be properly performed. Lengthened trot: A trot with lengthened strides. It differs from the more advanced extended trot in that it does not require the horse to bring its weight as far back on its hindquarters. Road trot or Show at Speed: As seen in roadster classes, is a gait similar to a racing trot, but much slower (suitable for an arena setting). The horse's head is collected, the stride is at maximum length, and the step is high and animated. Extended trot: An engaged trot with long strides where the horse stretches its frame and lengthens its strides to the greatest degree possible. The horse has a great amount of suspension. The back is round and the horse's head just in front and vertical. Racing trot: As seen in harness racing horses that race at a trot, such as Standardbred. The stride is at its maximum length with a great deal of suspension. The hind leg in a diagonal pair may begin to hit the ground before the front. Unlike the extended trot, the neck is not round but is extended out. , the North American speed record for a racing trot under saddle at one mile is 1:59, or Haute Ecole variations on the trot Two variations of the trot
