Known as the “sport of kings,” horse racing is one of the oldest pastimes in the world. This popular equestrian activity showcases the speed and endurance of equine athletes as they compete over a set distance, skillfully guided by jockeys.

Some horse breeds, such as the Thoroughbred, are bred specifically for racing. Thoroughbred racing is the most common type of horse racing in North America today, featured in popular events such as the Kentucky Derby.

While horse racing’s association with gambling has contributed to its popularity and economic impact, the racing industry still revolves around the horses at its heart. In recent years, concerns about horse welfare have brought changes to the industry. Ongoing efforts to improve safety help create better conditions for horses involved.

The excitement of race day continues to captivate audiences, offering excitement for enthusiasts of all kinds. Keep reading to learn more about racehorses and the history, traditions, and rules of horse racing.

History of Horse Racing

The history of horse racing traces back to ancient civilizations. As the sport spread across the world, different cultures developed their own horse racing traditions.

Chariot racing was a popular sport in ancient Greece. The Greek Olympic Games included both chariot and mounted horse racing by the 7th century BC. Archeological records suggest horse races were also held in Ancient Rome, Babylon, Arabia, Syria, and Egypt. [1]

Thoroughbred racing evolved in Great Britain, where breeders developed the Thoroughbred breed with the goal of creating the ideal racehorse. Racing became known as the “sport of kings” thanks to its popularity with British royalty and aristocrats. [2]

Organized horse racing was well-established in Great Britain by the 18th century when American settlers were importing Thoroughbreds to the colonies. [3]

The American Thoroughbred industry grew significantly in the 19th century and remained popular throughout the country after the Civil War. The first Kentucky Derby was held in 1875, making it the oldest continuously held sporting event in America. [3]

Sport Organizations

Organized Thoroughbred racing is overseen by sports organizations and breed registries that standardize rules, register thoroughbreds, and promote the industry.

The Jockey Club

The Jockey Club is the official breed registry of Thoroughbreds in North America. Incorporated in 1894, the club maintains The American Studbook. [3]

In addition to registering Thoroughbreds, the organization supports initiatives that aim to improve and drive interest in horse racing. [4]

Horseracing Integrity and Safety Authority

The Horseracing Integrity and Safety Authority (HISA) was established in 2020 to create a national set of rules that united state-based horse racing authorities. These include regulations related to racetrack safety, anti-doping, and medication control. [5]

Like other equestrian sport governing bodies, the HISA is a private, self-regulatory body. However, unlike those organizations, HISA was established by an act of Congress and is overseen by the Federal Trade Commission. [5]

Horseracing receives more scrutiny from the general public and government organizations than many equestrian sports due to its popularity and association with gambling. The legislation to create HISA entered Congress after a series of controversies threatened the future of the sport. [6]

National Steeplechase Association

The National Steeplechase Association is the official sanctioning body of U.S. steeplechase racing. The association has five standing committees that oversee safety, licensure, rules, promotions, and ratings. [7]

Types of Horse Races

The basic premise of horse races has remained unchanged for millennia. Races identify which horse can cover a specific distance the fastest. However, Thoroughbred races have different formats depending on the track surface, obstacles, and distance.

Flat Races

Flat races are the most widely recognized type of Thoroughbred horse racing. These races do not include obstacles and are the ultimate test of speed.

The term flat race is primarily used in the UK to distinguish this type of racing from others.

Distances can range significantly, but are typically held on an oval track. Track surfaces also vary, with dirt, grass, or all-weather polytrack making up the options for footing in modern racing.

Some examples of different types of flat races include: [8]

  • Classics: a group of five races specifically for three-year-old horses
  • Maidens: races restricted to horses who have yet to win a race
  • Handicaps: a race where each horse carries a different amount of weight, intended to ‘level the playing field’ and make the race more competitive

Eligibility for different races depends on horse sex, age, and ability.

Jump Races

A jump race is a test of jumping ability and stamina. Jump racing is less prevalent in North America than flat racing. These races include obstacles for horses to jump, known as hurdles or fences, and are typically longer than flat races.

Jump horses are typically older than flat horses. [9] Steeplechase is the most popular type of jump racing in North America. Obstacles in these events can include plain fences, water jumps, ditches, and hedges.

Race Day

Horse races are exciting events that draw large crowds of spectators, and the biggest events are often broadcast live on television. The fast-paced excitement can make it challenging for first-time racegoers to understand everything that happens on race day.

Rules

Horse racing rules are established by the HISA and state racing commission authorities in the United States. While regulations for different types of races vary, most events follow a similar set of basic rules. [10]

In flat racing, horses begin the race at a starting gate. The post time is when horses and jockeys are required to arrive at the gate, also known as the post.

Horses are assigned a number that corresponds to their post position. Post position number one is closest to the rail, the inside of the race track. Horses are led to their assigned post where they wait for the starting gates to open when the race begins.

All horses run the race simultaneously. The winner is determined by which horse crosses the finish line first, with some races coming down to a photo finish.

Eligibility

Different races have specific rules for horse eligibility. Some races are only open to horses of a certain age. For example, only three-year-olds can participate in the Triple Crown races: The Kentucky Derby, The Preakness, and The Belmont. [11]

A maiden race is only open to horses that have never won a race. However, these races can include horses of many different age groups. [8]

In handicap races, horses are “handicapped” by adding additional weight, called an impost, based on their previous performances and ability. This method is based on the concept of weight affecting the speed of a horse’s gallop, and if done correctly, all horses can compete equally in handicap races. [8]

A claims race only includes horses that are for sale, and participants must only race against horses that are selling for a similar price. At the end of the race, horses can be bought for the cost they were assigned. [8]

A claims race ensures fairness by grouping horses based on their assigned claiming price, requiring them to compete only against others of similar value and ability. This prevents more skilled horses from dominating lower divisions, as any horse performing too well risks being purchased at its claiming price.

Graded stakes races are considered the highest-class of races with the biggest prizes in North America. These races sometimes require horses to belong to the same age, sex, or even color. [12] Horses are typically required to carry the same weight in these events.

Jockeys

Jockeys are skilled riders who compete racehorses. Riding racehorses requires a high level of fitness and skill, and the jockey is often just as important as the horse in determining race outcomes.

Flat jockeys tend to be shorter and weigh less than other riders. A lighter jockey is easier for a young Thoroughbred to carry at high speeds. All jockeys must weigh out before a race to ensure horses carry the approved weight for the event.

Outriders

Jockeys aren’t the only riders on the racetrack. Every racetrack employs outriders, the mounted officials who escort racehorses before and after the race. Outriders are essential for horse and jockey safety. Horses are herd animals, and the calm outrider mounts help the young racehorses feel more secure.

These officials are also responsible for going after horses that lose their jockeys, preventing them from hurting themselves or others. Experienced outriders can catch a loose racehorse at high speeds and bring them to a stop in an incredible display of horsemanship.

Betting

Betting commonly occurs at Thoroughbred races where gambling is allowed. Bettors stake money on specific horses and win more if they bet correctly. Individuals can bet on horses to win, place, or show in North America.

A bet to win is also known as a straight bet. The bettor only wins if the horse comes in first place. A bet to place wins if the horse finishes first or second, while a bet to show wins if the horse finishes first, second, or third.

A straight bet offers the biggest payoff since winning is harder than placing or showing. Payoffs depend on the horse’s odds, determined by the total money wagered on each horse before race time.

Training

While Thoroughbreds are bred for racing, they still need training to bring out their best performance on the racetrack.

Early Stages

Thoroughbred racehorses begin training earlier than many riding horses. Most horses begin their racing careers at two years old, with the training process starting as early as 18 months of age.

While most Thoroughbreds are nearly fully grown at two, more research is needed to determine how early training influences growth and development. [13]

The backing process for racehorses is different from that of a riding horse. Once horses accept the rider on their back, they are taught to ride out in groups with older, experienced horses leading the way.

Some trainers teach the horses to canter in groups before giving the youngsters a break to mature physically and mentally.

Conditioning

Fitness and conditioning are essential for young racehorses. Before their racing careers begin, young horses are ridden by exercise riders at the walk, trot, and canter in both directions to help their muscles develop properly.

Cardiovascular fitness is developed on the exercise track, where horses build up to galloping race distances and learn to jump off and sprint. Proper conditioning is also critical for minimizing the risk of musculoskeletal injuries in racehorses. [14]

Racing

Racehorses must learn to settle in their gallop and listen to jockeys instead of running at top speeds with no particular direction or intent. Exercise riders work young horses alongside other racehorses to teach them to race and get comfortable running in a group.

Before young Thoroughbreds are ready to race, they must also learn to confidently enter the starting gate stalls and jump into a gallop at the starting bell. Training continues throughout a racehorse’s career to improve fitness and develop racing skills.

Retirement

While some racehorses have careers that last as long as they are sound, the average Thoroughbred flat racehorse retires from racing at age 4 or 5.

Successful racing Thoroughbred stallions and mares may become breeding horses. However, most retired racehorses move on to second careers.

Retired racehorses (a.k.a. Off The Track Thoroughbreds or OTTBs) need significant re-training to become successful riding horses. However, riding off-the-track Thoroughbreds can be incredibly rewarding. Many OTTBs have reached the top level of eventing and other riding disciplines.

Equipment

Horseracing jockey attire and horse tack differ significantly from the equipment most equestrians use with their riding horses.

Horse Tack

Racehorses wear lightweight jockey saddles with long, flat seats and small flaps. Traditional saddles are too heavy and restrictive for racing. The jockey rides with short stirrups, balancing above the horse during a race.

The saddle cloth displays the horse’s number for the race, and weight cloths are used to add weight when necessary. Racing bridles are also lightweight, with minimal padding. A wide variety of bits are permitted.

Some Thoroughbreds wear a hood with blinkers during races to help them focus and prevent them from spooking at distractions.

Jockey Attire

Horse racing is a dangerous sport. In one study, 706 professional jockeys reported more than 1,700 combined lifetime injuries. [15]

Helmets and protective vests are mandatory to minimize injury risks. Jockeys wear helmet covers and silks in colors that represent the horse’s owner. Racing pants protect their skin from friction while allowing them to move freely.

Riding boots for jockeys are flexible, permitting the short stirrup position. Racing goggles protect the jockey’s eyes from wind and footing kicked up by horses in front of them. Gloves are optional.

Racehorses

Racehorses are some of the most impressive athletes in the equine world. Providing Thoroughbreds with the best care and protecting horse welfare is essential for the future of horse racing.

Breeds

Thoroughbreds dominate horse racing. The breed was developed for speed, with centuries of selective breeding producing the unique conformation and temperament traits needed to excel on the racetrack.

While Thoroughbred racing is the most popular form of horse racing in North America, other horse breeds also participate in different forms of racing worldwide. These breeds include:

Ownership

For most of the sport’s history, racehorses were owned by aristocrats and other wealthy individuals. However, many successful racehorses in recent decades have been owned by syndicates and partnerships that make the sport accessible to more owners.

Thoroughbred youngsters are often sold at auctions by their breeders. The Keeneland September Yearling Sale is one of North America’s most popular Thoroughbred auctions.

Prices for promising young racehorses can reach seven figures, with average prices at top auctions over $100,000 USD. The high prices of top Thoroughbreds reflect the economic impact of the racing industry and the potential for a high return on investment within a short time frame. [16]

Management

Thoroughbred racehorses typically have more intense management than recreational horses. The breed is highly energetic and requires consistent exercise to develop sufficient fitness for racing.

Changes in routine that lead to decreased exercise or increased time spent in stalls can contribute to behavioral problems in young horses without a safe outlet for excess energy. However, overtraining can lead to injury.

Work with a qualified racehorse trainer to develop a training program that builds your horse’s fitness while permitting adequate time for recovery. In addition, like all horses, racehorses need consistent maintenance from a farrier and veterinarian to help keep them sound.

Another concern for racehorses is exercise induced pulmonary hemorrhage (EIPH). This condition is highly prevalent in actively racing horses and causes lung bleeding after intense exercise, leading to poor performance and permanent lung damage. [17]

Talk to your veterinarian if your horse gets nosebleeds or coughs after racing, which can be signs of EIPH.

Feeding

Racing requires high amounts of energy. Thoroughbreds are commonly fed high-grain diets at the track to meet these requirements. However, high intakes of grain can contribute to a higher risk of colic and gastric ulcers in racehorses.

One study found gastric ulceration in 86% of 345 studied racehorses. [18] Compromised gut function can cause discomfort and disrupt nutrient absorption needed to maintain performance.

The ideal feeding program for racehorses supports optimal gut health while providing the energy they need to run. Veterinary care and proper feeding strategies can complement a racehorse’s diet to support and maintain gut health. [19]
