Bonneville Speedway (also known as the Bonneville Salt Flats Race Track) is an area of the Bonneville Salt Flats northeast of Wendover, Utah, that is marked out for motor sports. It is particularly noted as the venue for numerous land speed records. The Bonneville Salt Flats Race Track is listed on the National Register of Historic Places.
The salt flats were first used for motor sports in 1912, but did not become truly popular until the 1930s when Ab Jenkins and Sir Malcolm Campbell competed to set land speed records.
A reduction of available racing surface and salt thickness has led to the cancellation of events at Bonneville, such as Speed Week in 2014 and 2015. Available racing surface is much reduced with just 2.5 miles (4.0 km) available instead of the 9-mile (14 km) courses traditionally used for Speed Week.
