Layout of Sonoma Raceway, the track where the race will be held.

Sonoma Raceway is a 1.99-mile (3.20 km) road course and drag strip located on the landform known as Sears Point in the southern Sonoma Mountains in Sonoma, California, U.S. The road course features 12 turns on a hilly course with 160 feet (49 m) of total elevation change. It is host to one of only seven NASCAR Cup Series races each year that are run on road courses. It is also host to the NTT 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.

In 2022, the race was reverted to racing the club configuration.[4]
