This folder contains accounts of the races that occurred at the Indianapolis Motor Speedway over the Memorial Day weekend in 1910. All the stars of the day attended, including Ray Harroun, Joe Dawson, Bob Burman and Barney Oldfield. Harroun won events for Marmon and Oldfield set a new track mile record in his world land speed racer, the “Lightning Benz,” otherwise known as the “Blitzen Benz.” This race also offered an obstacle course promoted by the Overland Motors Company. This entailed wooden ramps and a route that took cars off the Speedway’s course, into the infield and through the drainage ditch in the southwest turn. Ernie Moross was the Director of Contests and was responsible for developing the program of events.
