gallop, accelerated canter in which the rider’s weight is brought sharply forward as the horse reaches speeds up to 30 miles (50 km) an hour.
At the gallop, which usually averages 12 miles (20 km) an hour, the reins are held more loosely than at the canter, and the horse carries his head relatively high.
The gallop, which is a horse’s fastest gait, is usually a three-beat pace: the horse comes down first on one hind leg, then, simultaneously, on the diagonally opposite foreleg and the other hind leg, and finally on the other foreleg. A brief period of suspension, during which all four legs are off the ground, follows this sequence.
There may be four beats in an extended gallop, or run—the gait featured in cross-country riding, in polo, in working with cattle, and in track racing.
