New Hampshire Motor Speedway hosts the only NASCAR Sprint Cup Series, NASCAR Nationwide Series, and NASCAR Camping World Truck Series races held in the six state New England Region. The two NHMS NASCAR Sprint Cup Series events are regularly sold-out and have exceeded the NFL Super Bowl in attendance on every occasion they have been held. Over 50 hours of national television coverage of NHMS events is projected for 2008.
The track also hosts several regional professional Racing Series, including the NASCAR Camping World Series East and NASCAR Whelen Modified Tour, as well as amateur series for SCCA Sports cars, Championship Cup Series, Loudon RoadRace Series for motorcycles, and World Karting Association go-karts. Nationally recognized racing schools, such as The Richard Petty Driving Experience and The Penguin Roadracing School , have regularly scheduled sessions at "The Magic Mile".
