The term 'MODERATE RACE PACE' can be summarized by the crossword solution 'TROT', which is a four-letter word. Trotting is a type of gait in which a horse moves its legs in diagonal pairs, with the left front and right hind legs moving together, followed by the right front and left hind legs. It is a slower gait than a gallop, but faster than a walk. Trotting is often used in horse racing, as it allows for a moderate race pace.
