The land speed record (or absolute land speed record) is the highest speed achieved by a person using a vehicle on land. There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used, officiated by regional or national organizations under the auspices of the Fédération Internationale de l'Automobile (FIA).[1] The land speed record (LSR) is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes").[2] Two runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by at least one percent to be validated.[3]
