The Standardbred is a horse breed best known for its ability in harness racing at a trot or pace. Developed in North America, the breed can trace its bloodlines to 18th-century England. The breed name arose due to the "standard" required of breeding stock, to be able to trot or pace a mile within a certain time limit. Every Standardbred had to be able to trot a mile in less than two minutes and 30 seconds.
The breed is recognized worldwide. They are solid, well-built horses with good dispositions. In addition to harness racing, Standardbreds are also used in horse shows and for pleasure riding. They are also popular as light buggy horses for the Amish people, who eschew motorized vehicles.
