Indianapolis Motor Speedway
The Speedway reopened in 1910. Sixty-six automobile races were held during three holiday weekends (Memorial Day, Fourth of July and Labor Day). Each weekend featured two or three races of  to  distance. Several shorter contests were also held. Each race was its own event and earned its own trophy. All races were sanctioned by the AAA. In 1911, a change in marketing focus led to holding only one race per year.
