New Hampshire Motor Speedway is a 1.058-mile (1.703 km) oval speedway located in Loudon, New Hampshire, which has hosted NASCAR racing annually since 1990, as well as the longest-running motorcycle race in North America, the Loudon Classic. Nicknamed “”The Magic Mile””, the speedway is often converted into a 1.600-mile (2.575 km) road course, which includes much of the oval.
The track was originally the site of Bryar Motorsports Park before being purchased and redeveloped by Bob Bahre. The track is currently one of eight major NASCAR tracks owned and operated by Speedway Motorsports.
The track length is disputed by the two major series that run at New Hampshire. The NASCAR timing and scoring use a length of 1.058 miles (1.703 km). The IRL timing and scoring use a length of 1.025 miles (1.650 km).
