The Sonoma Raceway is home to some of the fastest racing in the country, and its 1,600 acres feature 900 yards for daily racing activities. NASCAR and Indy Car heavyweights such as Dan Gurney, Mario Andretti, Mark Donohue, Al Unser, Jeff Gordon, Mark Martin and Dale Earnhardt have all driven, won and set records at the racetrack, and the Raceway hosts a plethora of events during the year.
Infineon Raceway is located north of the Golden Gate Bridge in Sonoma Valley. The track hosts several nationally televised events, including NASCAR Winston Cup, National Hot Rod Association (NHRA) drag racing, the American Le Mans Series, and the American Motorcycle Association (AMA) Superbike Tour. The racetrack hosts a year-round motorsports complex with events scheduled 340 days and 50 weekends a year. More than one-half million fans passed through the gates during the 2007 season.
