The term 'PACE BETWEEN A WALK AND A RUN' can be summarized as a TROT, which is a four-letter word. A TROT is a gait of a horse in which the legs move in diagonal pairs, with the left hind and right forelegs moving together followed by the right hind and left forelegs. It is a two-beat gait, meaning that there are two feet on the ground at all times. Trotting is faster than walking but slower than running, making it the perfect pace between a walk and a run.
