Dorothy Levitt, in a 19 kW (26 hp) Napier, at Brooklands, England, in 1908.

Land speed racing is a form of motorsport. Land speed racing is best known for the efforts to break the absolute land speed record, but it is not limited to specialist vehicles. [1] A record is defined as the speed over a course of fixed length, averaged over two runs (commonly called "passes"). [2]
The distance used for calculating the overall speed record is usually the distance in a straight line. [2] In the case of man-powered races, overall speed record doesn't always reflect the best performance. It is highly dependent on technological advantages generating the speed of the craft, vessel or vehicle. [3]
