A horse race is a form of thoroughbred horse racing that pits one or more horses against each other. The contest is a long-standing tradition that dates back to ancient times, when people used steeds as transportation and battle stallions. It is popular worldwide and is a major source of entertainment, drawing millions of spectators to the track. The competition is regulated by state and federal laws.
The sport is a multibillion-dollar industry that generates revenue from betting, concession sales, licensing for TV and simulcast and sponsorships. Some of the most prestigious events are held at exclusive European venues like Royal Ascot. Spectators attend the races in lavish attire, wearing fancy hats and drinking mint juleps. The Kentucky Derby, which takes place on the first Saturday in May each year, is the most famous of these races.
Despite the glamour of high-profile events, horse racing is not without its dark side. Behind the glamorous facade, horses are pushed beyond their limits, often under threat of whips and illegal electric shock devices. Many of these animals will sustain injuries or suffer gruesome breakdowns, including traumatic pulmonary hemorrhage, in which blood from the lungs pours out of their bodies. They are also fed cocktails of legal and illegal drugs intended to mask injuries and enhance performance. Ultimately, many are sent to slaughter.
In addition to the horses themselves, the sport relies heavily on the work of trainers and jockeys. Those with the most experience and skill can achieve unparalleled success, while others find it more difficult to succeed in the demanding profession.
To improve their chances of winning, trainers try to select horses that are well suited for the particular conditions of each race. The most important factors are speed, stamina and the ability to run under pressure. Trainers will also try to avoid selecting horses with injury issues, such as arthritic joints.
Horses compete in a number of different types of races, depending on the size of the purse and the rules of each jurisdiction. Some races are run on dirt, others on grass and still more on a synthetic surface known as an all-weather track. Each track has its own unique characteristics that influence the performance of the horses.
It is widely believed that horses improve by 22.2 points between their second and third year, with a peak at the spring of their three-year-old season. They then decline by 12.1 points on average from their peak age category. In 2023, three of the horses that earned the highest speed figure of their careers did so at nine years of age. One of those was Sunshine Bear, who won by 14 lengths with a career-high figure of 91 at 9.3 years of age. The other two were Messenger Springs, who won at 9.46 years of age, and My Friend Jim at 9.94 years of age. These figures are calculated using a proprietary software called the Horse Racing Laboratory (HRL). A horse with a higher HRL score is expected to perform better than one with a lower HRL score.
