In addition to designing passenger cars, Fred and Augie Duesenberg were involved in auto racing for more than a decade. Although Fred was no longer driving racecars by 1912, he remained active for another twelve years as a racecar designer and team owner. In April 1920 a Duesenberg racecar driven by Tommy Milton set a land-speed record of for a measured mile on the sands at Daytona Beach, Florida. In 1921 Jimmy Murphy drove a Duesenberg racer to become the first American car to win the prestigious Grand Prix at Le Mans, France. Duesenberg-made entries also participated in Indianapolis 500-mile auto races between 1912 and 1932, including winning the annual event at the Indianapolis Motor Speedway in 1924, 1925, and 1927 before Fred Duesenberg retired from racing in 1931.
