NASCAR's 23^rd consecutive visit to the Sonoma Valley headlines the 2011 Big O Tires Racing Season at Infineon Raceway.  The seven-race major event schedule, one of the most comprehensive in the country, will be highlighted by three of the top racing series in the country - the NASCAR Sprint Cup Series, NHRA Full Throttle Drag Racing Series and IZOD IndyCar® Series. 

Located just 30 minutes north of the Golden Gate Bridge in San Francisco, the 1,600-acre facility serves as the gateway to the beautiful Sonoma Wine Country.

In addition to its slate of major events, Infineon Raceway is a year-round motorsports complex with events scheduled 340 days and 50 weekends a year. More than one-half million fans pass through the gates each year
