The Cotati Speedway was a 1.25-mile (2.01 km) wooden board track for automobile racing in Cotati, California. The track was built and opened in 1921, and featured heavily banked turns, which were around 41.5° at their steepest. It hosted six AAA Championship Car races across 1921 and 1922. Despite the popularity of the sport, the Cotati Speedway failed to attract the size of crowds the organisers had hoped for, partly due to the track's location. In December 1922, primarily for financial reasons, the track was shut down. Despite attempts by some locals to save the track, it was dismantled the following year, with much of the timber reclaimed and sold for other projects.
