Flat racing is a form of horse racing which is run on a level racecourse. It is run over a predetermined distance from 2 furlongs (402 m) up to 3 miles (4,828 m) and is either test of speed, stamina or both, whilst the skills of the jockey is determined by his ability to restrain the horse or impel it.
Many different horse breeds are used in flat racing worldwide, but the Thoroughbred is the most dominant. The races take place on track surfaces suitable for horses. Worldwide, the most common is a natural grass surface, called "turf". In North America, the most common surface is a harrowed "dirt" surface, often based primarily on a mixture of sand and local soil. Most winter flat races in Britain and other parts of the world are run on a synthetic or all-weather surface, generally a blend of sand with synthetic fiber and/or rubber, often coated with wax or a similar substance.
