Horse-racing

Horse-racing is an equestrian sporting activity which has been practiced over the centuries; the chariot races of Roman times were an early example, as was the contest of the steeds of the god Odin and the giant Hrungnir in Norse mythology. It is often inextricably associated with the activity of wagering on the outcome of a race, gambling.

There are two chief types of racing involving horses; thoroughbred racing and harness racing. Other types of horse race on which wagers are taken include races between quarter horses and between cold-blooded trotting horses.

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. Exceptional horses can win millions of dollars and make millions more by providing stud services, such as horse breeding.

The style of racing, the distances and the type of events varies very much by the country in which the race is occurring and many countries offer different types of horse-race.

In the United Kingdom for example, there are races which involve obstacles (either hurdles or fences) called steeplechase and those which are unobstructed races over a given distance (flat racing). See also United Kingdom horse-racing.

In the United States, races can occur on flat surfaces of either dirt or grass, generally thoroughbred racing; certain tracks also offer quarterhorse racing and harness racing. Racing with other breeds, such as Arabian horse racing, is found on a limited basis. The high point of US horse racing is the Kentucky Derby which, together with the Belmont Stakes and the Preakness Stakes, form the Triple Crown. Betting on horse racing is usually sanctioned and regulated by state governments through legalized parimutuel gambling.

Thoroughbred horse racing in the United States has its own Hall of Fame for horses, jockeys, and trainers.

Some of the world's most famous thoroughbred racehorses include:

Celebrated standardbred racehoses include:

In Australia the most famous horse is Phar Lap. However, this horse is from New Zealand, as was Cardigan Bay, a pacing horse who enjoyed great success at the highest levels of American harness racing in the 1960s. Racing in Australasia has enjoyed great success with races such as the Melbourne Cup, which has recently been attracting many international entries. See also: Australian horse-racing.

The most famous horses from Canada are Northern Dancer, who after winning the Kentucky Derby and Preakness went on to become the most successful Thoroughbred sire ever, and his son Nijinsky II. In Canada, however, harness racing is more popular than Thoroughbred racing. Woodbine Racetrack in Toronto, home of the Queen's Plate, Canada's premier thoroughbred stakes race, and the North America Cup, Canada's premier standardbred stakes race, is the only race track in North America which stages Thoroughbred and Standardbred (harness) meetings on the same day.

In Ireland, noted for its great racing history, the Derby winning Thoroughbred race horse Shergar was kidnapped on February 8, 1983. He has never been found.
