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 the early 1990s, 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 1.6-mile (2.6 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, Inc. .

In 2000, the track was the site of a pair of fatal collisions which took the lives of two promising young drivers. In May, while practicing for a Busch Series race, Adam Petty perished when his throttle stuck exiting the second turn, resulting in a full speed crash head-on in the middle of the third and fourth turns. When the NASCAR Cup Series made their first appearance of the season, a similar fate befell 1998 Rookie of the Year Kenny Irwin, Jr. For safety reasons, track owners decided to run restrictor plates on the cars during their return trip to the speedway in September 2000. This resulted in an uneventful Dura Lube 300 won by Jeff Burton, which had no lead changes, was the result of the experiment. It was the first wire-to-wire race since the 1970s.
