Gypsy, the Equine Encyclopedia, has something to say about the gallop. Like all shetlands, she is always watching, learning and listening.
The gallop is the horse’s fastest gait. It is well known in horse racing and Quarter horses running a quarter-mile have clocked speeds up to 50 miles per hour.
At the gallop, some thoroughbred racehorses have stride lengths over 25 feet. A more collected form of gallop, the Hand-Gallop is sometimes used in hutseat classes at horse shows.
The gallop is a 4-beat gait and horses have only one foot on the ground at a time with a long “period of suspension” (all feet off the ground).
Most ponies are lazy and would never, never gallop.
