Mallory Park is a motor racing circuit situated in the village of Kirkby Mallory, just off the A47, between Leicester and Hinckley, in central England. Originally used for grass-track until 1955, a new, basically oval hard-surfaced course was constructed for 1956, with a later extension forming a loop with a hairpin bend. With the car circuit measuring only 1.35 miles (2.173 km) it is amongst the shortest permanent race circuits in the UK. However, chicanes introduced to reduce speeds in motorcycle events mean that the Superbike Circuit is now slightly longer, at 1.41 miles (2.269 km). Shorter UK circuits are Lydden Hill, Brands Hatch Indy circuit, Scotland's Knockhill and Silverstone's diminutive Stowe circuit.
