Key points
- The Standardbred is an American horse breed developed in the 19th century specifically for harness racing.
- The breed name originates from an 1879 registry rule requiring horses to meet a standard speed of one mile in 2 minutes and 30 seconds.
- Nearly all modern Standardbreds trace their lineage back to a single foundation sire, Hambletonian 10.
- Standardbreds race at two distinct gaits, the diagonal trot and the lateral pace, with pacers being more common in North American racing.
- Compared to Thoroughbreds, Standardbreds are lower to the ground, more muscular, heavier-boned, and possess a highly cooperative temperament.
What is a Standardbred Horse?
The Standardbred is a distinct American horse breed best known for its dominance in harness racing. Unlike Thoroughbred racing, where jockeys ride horses under saddle at a gallop, harness racing features Standardbreds pulling a driver in a lightweight, two-wheeled cart called a sulky.
While they are famous for their speed and stamina on the racetrack, Standardbreds are also celebrated for their sensible minds and physical durability. This combination of athletic ability and a calm disposition makes them highly valued both during their racing careers and in their lives after the track.
Why is it Called a 'Standardbred'?
The name of the breed comes from the specific entry requirements established for its official registry in 1879. To be registered by the National Association of Trotting Horse Breeders, which preceded the United States Trotting Association, a horse had to meet a strict performance standard.
This standard required the horse to trot or pace a distance of one mile in 2 minutes and 30 seconds or less. Horses that could meet this speed standard were admitted into the studbook, and the breed became known as the Standardbred.
The genetic foundation of the breed rests almost entirely on one horse: Hambletonian 10. Born in 1849, this stallion was a great-grandson of the imported English Thoroughbred Messenger. Hambletonian 10 did not have a extensive racing career himself, but he possessed remarkable prepotency, passing on his speed, muscular build, and trot-oriented gaits to his offspring. He sired over 1,300 foals, and virtually every modern Standardbred racing today can be traced back to him.
Key Characteristics of the Standardbred Breed
The physical build of the Standardbred reflects its history as a working and racing animal. They are built for power, leverage, and sustained speed over distance.
Standardbred Horse Height and Weight
The average Standardbred horse height ranges from 14 to 17 hands, which is approximately 56 to 68 inches at the highest point of the shoulder. They typically weigh between 900 and 1,000 pounds.
Physical Build
Standardbreds are characterized by a long, deep body, a strong back, and powerful hindquarters that provide the driving force for their gaits. They have heavier bones and flatter joints than Thoroughbreds, which contributes to their legendary physical soundness and resistance to injury. Their heads are refined but often larger and less chiseled than those of riding breeds, featuring long, expressive ears and a calm eye.
Temperament
The temperament of the Standardbred is one of its most defining traits. They are famously docile, willing, and sensible. Because harness racing requires horses to race in close quarters while pulling equipment, breeders have long selected for horses that remain calm under pressure and respond reliably to their drivers.
Standardbred Horse Pros and Cons
For prospective owners and handicappers alike, the breed has clear characteristics to consider:
- Pros: Exceptional durability, calm and level-headed temperament, high trainability, and excellent stamina.
- Cons: A flatter jumping style compared to specialized sport horses, and a natural tendency to pace rather than canter, which requires patient retraining for traditional riding disciplines.
The Two Racing Gaits: Trotters vs. Pacers
In harness racing, Standardbreds compete in two distinct categories based on their gait: trotters and pacers. A gaited horse is bred to move in a specific, highly coordinated footfall pattern at high speeds without breaking into a gallop.
Trotters
Trotters move their legs in diagonal pairs. When the front left leg moves forward, the rear right leg moves forward simultaneously. This is a natural two-beat gait found in all horse breeds, but racing trotters have been selectively bred to maintain this gait at speeds exceeding 30 miles per hour. Major events like the Hambletonian are dedicated exclusively to trotters.
Pacers
Pacers move their legs laterally, meaning the legs on the same side of the body move together. The front left and rear left legs move forward at the same time, followed by the front right and rear right. This lateral movement produces a distinctive side-to-side swaying motion.
Pacing is slightly faster and more energy-efficient than trotting, and pacers make up the vast majority of harness racing entries in North America. To help them maintain this gait at high speeds without tripping or breaking stride, pacers usually wear plastic straps called hopples. Legendary pacers like Dan Patch in the early 20th century captured the public imagination by setting speed records that stood for decades.
Standardbred vs. Thoroughbred: What is the Difference?
While both breeds excel at racing, they are built, trained, and raced differently. Understanding these distinctions is essential for handicappers looking to apply their knowledge to harness racing.
- Physical Build: Standardbreds are generally shorter, more muscular, and heavier-bodied with longer backs. Thoroughbreds are taller, leaner, and built for explosive, long-strided galloping.
- Racing Style: Standardbreds compete in harness racing, pulling a driver in a sulky at a trot or a pace. Thoroughbreds compete in flat or steeplechase racing, carrying a jockey on their back at a full gallop.
- Temperament: Standardbreds are known for their patient, steady, and sensible disposition. Thoroughbreds tend to be more sensitive, reactive, and high-strung.
- Stamina and Recovery: Standardbreds possess immense stamina and can often race multiple heats in a single day or back-to-back weeks with minimal wear. Thoroughbreds require longer rest periods between races due to the high-impact nature of galloping under weight.
Life After the Track: Post-Racing Careers
Standardbreds enjoy highly successful second careers when their racing days are over. Because of their calm demeanor and exposure to traffic, crowds, and various equipment during their racing careers, they transition easily to new environments.
Organizations like the Standardbred Retirement Foundation work to retrain and rehome retired racehorses. Standardbreds excel in trail riding, competitive driving, dressage, and endurance riding. Their steady temperament also makes them excellent therapy horses and reliable family companions.
Frequently Asked Questions
Is a Standardbred a warmblood?
Yes. Standardbreds are classified as warmbloods. This term refers to horses that combine the calm strength of cold-blooded draft breeds with the speed, agility, and spirit of hot-blooded ancestral breeds like the Thoroughbred and Arabian.
Do Standardbreds make good pets?
Standardbreds make excellent pets and riding companions. Their sensible nature, patience, and cooperative attitude make them highly suitable for riders of all experience levels, including beginners and families.
What is the difference between a Standardbred and an American Saddlebred?
While both are American breeds with historical connections, they serve different purposes. The Standardbred is bred for speed and stamina in harness racing at the trot or pace. The American Saddlebred is bred primarily for show ring performance, riding, and driving, and is known for its high-stepping, elegant action and specialized riding gaits like the slow gait and the rack.
Harness Racing Insights
For handicappers, understanding the physical traits and gait mechanics of the Standardbred is a valuable asset. The difference between a trotter's diagonal stride and a pacer's lateral movement affects how they handle track conditions, navigate turns, and maintain speed.
