A race track (or 'racetrack', 'racing track' or 'racing circuit') is a facility built for racing of vehicles, athletes, or animals (e.g. horse racing or greyhound racing). A race track also may feature grandstands or concourses. Racetracks are also used in the study of animal locomotion. Some motorsport tracks are called speedways.
A racetrack is a permanent facility or building. Racecourse is an alternate term for a horse racing track, found in countries such as the United Kingdom, India, Australia, Hong Kong, and the United Arab Emirates. Race tracks built for bicycles are known as velodromes. Circuit is a common alternate term for racetrack, given the circuit configuration of most race tracks, allowing races to occur over several laps.
A race course, as opposed to a racecourse, is a term for non-permanent tracks for sports, particularly road running, water sports, road racing, or rallying. Many sports usually held on racetracks also can occur on temporary tracks, such as the Monaco Grand Prix in Formula One.
There is some evidence of racetracks being developed in several ancient civilizations. The most developed ancient racetracks were the hippodromes of the Ancient Greeks and the circuses of the Roman Empire. Both of these structures were designed for horse and chariot racing. The stadium of the Circus Maximus in Ancient Rome could hold 200,000 spectators.
