Sonoma Raceway

Sonoma Raceway is a road course and dragstrip located at Sears Point in the southern Sonoma Mountains of Sonoma County, California. The road course features 12 turns on a hilly course with 160 ft of total elevation change. 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 north of San Francisco and Oakland.

With the closure of Riverside International Raceway in Moreno Valley, California after the 1988 season, NASCAR wanted a West Coast road course event to replace it, and chose the Sears Point facility. Riverside Raceway was razed for the Moreno Valley Mall.
