The 2,52 mile course was constructed on 720 acres by Marin County owners Robert Marshall, Jr., an attorney from Point Reyes, and land developer Jim Coleman of Kentfield. It only took four months from breaking ground to the first race. The track was then sold to Filmways Corp., a Los Angeles-based entertainment company for 4.5 million. From 1969 through early 1970, the Raceway hosted a variety of events, including USAC IndyCar races, NASCAR stock car races, and drag races. Then, one of the most significant moves in the track's history occured. The raceway signed a five-year contract with the National Hot Rod Association for the California Nationals. The first event was held in the summer of 1988. Additional buildings constructed on the property brought shop space to more than 700,000 square feet. In 1989, NASCAR Winston Cup Series debuted at the raceway, with Ricky Rudd taking the inaugural victory. Major renovations began with the creation of " The Chute," an 890 -foot high-speed stretch that will be used for all NASCAR -sanctioned events. The stretch connects existing turns 4 and 7 and was officially opened on May 5 by NASCAR star Jeff Gordon. The re-design of the road course shortens the circuit from 2.52 miles to 1.949 miles, but increases the Winston Cup race from 74 to 112 laps, providing fans with more action. The chute will be used for NASCAR Nextel Cup, NASCAR Winston West, NASCAR Southwest Series and NASCAR Craftsman Truck series events.
