About Sonoma Raceway
Infineon Raceway's 12-turn, 2.22-mile course is located 30 minutes north of the Golden Gate Bridge in San Francisco and is close to Sonoma Wine Country. The track hosts several nationally televised events, including NASCAR NEXTEL Cup, National Hot Rod Association (NHRA) drag racing, the American Motorcycle Association (AMA) Superbike tour, and the IRL IndyCar Series. Infineon Raceway is a year-round motorsports complex with events scheduled 340 days and 50 weekends a year. AMA uses a modified 2.22 mile track with 14 turns, 9 right and 5 left. It skips part of the Esses and shortens the hairpin (Turn 11) to provide additional safety for motorcyclists by adding runoff room. The original Turn 11 does not have any runoff.
