The Standardbred is a breed of horse known for its speed and endurance, primarily used in harness racing. These horses are recognized for their unique gait, particularly the trot and pace, which allows them to race efficiently while pulling a sulky. Standardbreds are typically calm and friendly, making them great companions for both racing and recreational riding. Originating in the United States in the 19th century, the Standardbred was developed from a mix of Thoroughbred and Morgan horses. They are often seen in various equestrian disciplines beyond racing, including dressage and show jumping. Their versatility and gentle nature make them popular among horse enthusiasts.
