New Hampshire Motor Speedway is a 1.058-mile oval speedway located in Loudon, New Hampshire which has hosted NASCAR™ racing annually since the early 1990s, as well as an IndyCar weekend and the oldest motorcycle race in North America. The speedway is located in Loudon, N.H., on Route 106, about 10 miles north of Concord, N.H. The track has been described as "Martinsville on steroids" and is considered by most drivers as one of the toughest ovals in motorsports.
The track opened as New Hampshire International Speedway in June 1990. The existing road circuit was redeveloped into a multi-purpose track, with NASCAR™ added to the popular Loudon Classic motorcycle, WKA go-kart and SCCA races on the complex. It was the largest speedway in New England, and later expansion has made it the largest sports venue of any type in the region.
