Trotting on a horse is a two-beat gait in which the horse’s legs move in diagonal pairs, with the inside hind leg and outside foreleg moving simultaneously, followed by the outside hind leg and inside foreleg. It is a faster gait than walking but slower than cantering or galloping.
Trotting is a very comfortable gait for both the horse and the rider. It is also a very efficient gait, as it allows the horse to cover a lot of ground with relatively little effort. Trotting is often used for long-distance riding, as it is less tiring for the horse than faster gaits.
