Sunday 14th August 1921
The first race was held at the Cotati Speedway in Santa Rosa, California, US. Eddie Hearne in a Duesenberg-Distil won the 150-mile event. It was a mile-and-a-quarter around with 38 degree banked corners, built of 2,000,000 feet of lumber. Because of poor transportation to the area for spectators, it failed. It was replaced by an egg farm, which was later torn down to make way for a housing development.
