Horse racing is an equestrian sport that has been practiced over the centuries; the chariot races of Roman times are an early example, as is the contest of the steeds of the god Odin and the giant Hrungnir in Norse mythology. It is inextricably associated with gambling. The common sobriquet for Thoroughbred horse racing is The Sport of Kings.
One of the principal forms of horse racing, which is popular in many parts of the world, is Thoroughbred racing. Harness racing for Standardbred horses is also popular in Australia, New Zealand, the eastern United States and more popular than Thoroughbred racing in Canada and parts of Europe. Thoroughbred racing is done on the flat or over jumps, as steeplechasing or hurdles races. Quarter horse racing is also popular in the western United States and Florida. Racing with purebred Arabian horses exists in several states in the United States, as well as in most of Europe and the Middle East. This form of racing is known as endurance racing.
The different types of racing all concern different breeds of horses. The Thoroughbred races moderate distances at very fast paces. The Standardbred horses use their ability to race in harness at a trot or pace instead of under saddle at a gallop. The Quarter Horse is involved in short distance sprinting while the Arabian is involved in endurance racing. These four different breeds of horses possess different muscle structures that make them suitable for their type of racing. These horses race on various track surfaces ranging from dirt to synthetic polytrack.
The breeding, training and racing of horses in many countries is now a significant economic activity as, to a greater extent, is the gambling industry which is largely supported by it. The time invested in training these horses is extensive and varies according to the type of race the horse is involved in. Exceptional horses can win millions of dollars and might make millions more by providing stud services, such as horse breeding.
Horse racing in Australia was founded during the early years of settlement and the industry has grown to be among the top three leading Thoroughbred racing nations of the world. The world famous Melbourne Cup, the so-called race that stops a nation, has recently attracted many international entries. In country racing, records indicate that Goulburn commenced racing in 1834. Australia's first country racing club was established at Wallabadah in 1852 and the Wallabadah Cup is still held on New Year's Day (the current racecourse was built in 1898).
In Australia, the most famous horse was Phar Lap, who raced from 1928-1932 (though originally bred in New Zealand). Phar Lap carried 9st 12lb (62.5 kg) to win the 1930 Melbourne Cup. Australian steeplechaser Crisp is remembered for his battle with Irish champion Red Rum in the 1973 Grand National. In 2003-2005 the mare Makybe Diva (originally bred in the United Kingdom) became the only racehorse to ever win the Melbourne Cup three times, let alone in consecutive years. In harness racing, Paleface Adios became a household name during the 1970s, while Cardigan Bay, a pacing horse from New Zealand, enjoyed great success at the highest levels of American harness racing in the 1960s.
