A race track (or 'racetrack' or 'racing track') is a purpose-built facility for racing. This racing can be of animals (eg. horse racing or greyhound racing), automobiles, motorcycles or athletes. A race track may also feature grandstands or concourses. The term racecourse is also used for horse-racing facilities. Race tracks built for bicycles are known as velodromes.
Horse and dog racing facilities tend to use circular or oval tracks, whereas most automotive and motorcycle racing is performed on meandering courses, which are sometimes called 'road circuits' (this originates in the fact that the earliest road racing circuits were simply closed-off public roads). A notable exception is most forms of automotive racing in the USA (such as NASCAR) that primarily use oval tracks (known as "speedways").
