Road racing
In North America, road racing is motor racing held on a paved closed circuit with both left and right turns. Road racing is therefore distinct from both off-road racing and oval track racing; the latter is common in North America and involves turning in only one direction (usually left, counter-clockwise). Road racing may be on purpose-built race tracks (called road courses) or on temporary circuits, such as closed-off airport runways and public roads, typically street circuits. A "roval" is a road course incorporating parts of an oval track and its infield, such as is used for the 24 Hours of Daytona at Daytona International Speedway.
In British English, the term is usually used for short circuit events held at purpose-built facilities typically of one to three miles in length, often with scenic, landscaped surroundings resembling parkland. Many older facilities were based on disused former-airfields after [World War II]] and have fallen into disrepair and been re-purposed and built-over, and, although some have endured for closed-to-club and British national events, only Silverstone, having benefitted from a massive redevelopment, is of international standard.
