The Sports Car Club of America heads to Sonoma Raceway for the first time for the National Champion Runoff. Taking place over six, action packed days, the National Champion Runoff has become known as the American amateur sports event of the year. Since 1964, the SCCA has crowned Road Racing National Champions through the winner-take-all Runoffs format.
As host of the 55th Runoffs in 2018, Sonoma Raceway becomes only the third California track to host the SCCA’s National Championship.
