Horse racing in the United States

Horse racing in the United States dates back to 1665, which saw the establishment of the Newmarket course in Salisbury, New York, a section of what is now known as the Hempstead Plains of Long Island, New York. This first racing meet in North America was supervised by New York's colonial governor, Richard Nicolls. The area is now occupied by the present Nassau County, New York, region of Greater Westbury and East Garden City.

Horse racing remains a popular sport throughout the United States.

In 1665, the first racetrack was constructed on Long Island. It is the oldest Thoroughbred race in North America. The American Stud Book was started in 1868, prompting the beginning of organized horse racing in the United States. There were 314 tracks operating in the United States by 1890; and in 1894, the American Jockey Club was formed. The anti-gambling sentiment prevalent in the early 20th century led almost all states to ban bookmaking. Bookmaking is the process of taking bets, calculating odds, and paying out winnings. This nearly eliminated horse racing altogether. When parimutuel betting was introduced in 1908, the racing industry turned around. Horse racing flourished until World War II. The sport did not regain popularity in the United States until horses began to win the Triple Crown. The Triple Crown is a series of three races, consisting of the Kentucky Derby, the Preakness Stakes, and the Belmont Stakes.

Contemporary organized Endurance racing began in California around 1955, and the first race marked the beginning of the Tevis Cup This race was a one-hundred-mile, one-day-long ride starting in Squaw Valley, Placer County, and ending in Auburn. Founded in 1972, the American Endurance Ride Conference was the United States' first national endurance riding association.
