Sonoma Raceway, formerly Sears Point Raceway and Infineon Raceway is a 2.52-mile (4.06km) road course and drag strip located on the landform known as Sears Point in the southern Sonoma Mountains near Sonoma, California, USA. The road course features 12 turns on a hilly course with 160 feet of total elevation change. It is host to one of only five national NASCAR races each year that are run on road courses (including two races at Watkins Glen International in Watkins Glen, New York and the Nationwide Series-only races at Circuit Gilles Villeneuve in Montreal, Quebec, Canada and Road America in Elkhart Lake, Wisconsin). It is also host to the IZOD IndyCar 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 which may or may not be open to the general public. The largest such car club is the Sports Car Club of America.
