Sonoma Raceway (originally known as Sears Point Raceway, Golden State International Raceway and Infineon Raceway) is a road course and dragstrip located at Sears Point in the southern Sonoma Mountains of Sonoma County, California.[1] The road course features 12 turns on a hilly course with 160 ft (49 m) of total elevation change.[3] It is host to one of the few NASCAR Cup Series races each year that are run on road courses. It has also played host to the IndyCar Series, the NHRA Mission Foods Drag Racing Series, and several other auto races and motorcycle races such as the American Federation of Motorcyclists series. Sonoma Raceway continues to host amateur, or club racing events with some open to the public. The largest such car club is the Sports Car Club of America. The track is 30 mi (48 km) north of San Francisco and Oakland.
