Thoroughbred racing is a sport and industry involving the racing of Thoroughbred horses. It is governed by different national bodies. There are two forms of the sport – flat racing and jump racing, the latter known as National Hunt racing in the UK and steeplechasing in the US. Jump racing can be further divided into hurdling and steeplechasing.
Ownership and training of racehorses
Traditionally, racehorses have been owned by wealthy individuals. It has become increasingly common in the last few decades for horses to be owned by syndicates or partnerships. Notable examples include the 2005 Epsom Derby winner Motivator, owned by the Royal Ascot Racing Club, 2003 Kentucky Derby winner Funny Cide, owned by a group of 10 partners organized as Sackatoga Stable, and 2008 Kentucky Derby winner Big Brown, owned by IEAH stables, a horse racing hedgefund organization.
Historically, most race horses have been bred and raced by their owners. Beginning after World War II, the commercial breeding industry became significantly more important in North America, Europe and Australasia, the result of which being that a substantial portion of Thoroughbreds are now sold by their breeders, either at public auction or through private sales. Additionally, owners may acquire Thoroughbreds by "claiming" them out of a race (see discussion of types of races below).
A horse runs in the unique colours of its owner. These colours must be registered under the national governing bodies and no two owners may have the same colours. The rights to certain colour arrangements ("cherished colours") are valuable in the same way that distinctive car registration numbers are of value. It is said that Sue Magnier (owner of George Washington, Galileo etc.) paid £50,000 for her distinctive dark blue colours. If an owner has more than one horse running in the same race then some slight variant in colours is often used (normally a different coloured cap) or the race club colours may be used.
The horse owner typically pays a monthly retainer or, in North America, a "day rate" to his or her trainer, together with fees for use of the training center or gallops (if the horse is not stabled at a race track), veterinarian and farrier (horseshoer) fees and other expenses such as mortality insurance premiums, stakes entry fees and jockeys' fees. The typical cost of owning a race horse in training for one year is in the order of £15,000 in the United Kingdom and as much as $35,000 at major race tracks in North America.
The facilities available to trainers vary enormously. Some trainers have only a few horses in the yard and pay to use other trainers' gallops. Other trainers have every conceivable training asset. It is a feature of racing that a modest establishment often holds its own against the bigger players even in a top race. This is particularly true of national hunt racing.
Values
In 1976, Canadian Bound became the first Thoroughbred yearling racehorse ever to be sold for more than US$1 million when he was purchased at the Keeneland July sale by Canadians, Ted Burnett and John Sikura Jr.
Organizations
Ireland
Racing is governed on an All-Ireland basis, with two bodies sharing organising responsibility. The Irish Horseracing Regulatory Board is the rulemaking and enforcement body, whilst Horse Racing Ireland governs and promotes racing. In 2013, Ireland exported more than 4,800 Thoroughbreds to 37 countries worldwide with a total value in excess of €205 million ($278 million). This is double the number of horses exported annually from the U.S.
Great Britain
In Great Britain, Thoroughbred horse racing is governed by the British Horseracing Authority (BHA) which makes and enforces the rules, issues licences or permits to trainers and jockeys, and runs the races through their race course officials. The Jockey Club in the UK has been released from its regulatory function but still performs various supporting roles.
A significant part of the BHA's work relates to the disciplining of trainers and jockeys, including appeals from decisions made by the course stewards. Disciplinary enquiries usually relate to the running of a horse, for example: failure to run a horse on its merits, interference with other runners, excessive use of the whip. The emergence of internet betting exchanges has created opportunities for the public to lay horses and this development has been associated with some high-profile disciplinary proceedings.
