Mallory Park

Mallory Park is a motor racing circuit situated in the village of Kirkby Mallory, just off the A47, between Leicester and Hinckley. With the full car circuit measuring only 1.35 miles (2.173 km) it is the second shortest permanent race circuit in the UK. However, chicanes introduced to reduce speeds in motorcycle events mean that the Superbike Circuit is slightly longer, at 1.41 miles (2.269 km). The only shorter UK circuit is at Lydden Hill.
