The term 'moderate gait' refers to the speed of a horse's movement. It is a combination of two different gaits, the TROT and the CANTER. The TROT is a two-beat gait in which the horse moves its legs in diagonal pairs, with one foot always on the ground. The CANTER is a three-beat gait in which the horse moves its legs in a sequence of three, with one foot always on the ground. Together, these two gaits create a moderate gait that is neither too slow nor too fast.
