Indianapolis Speedrome
The Indianapolis Speedrome is the oldest operating figure 8 track in the United States as it opened in 1941. It is believed by many historians that this is the first figure 8 track where cars intersect.
The Speedrome is home to the World Figure 8 Championships, the Annual Spring Shootout, and the 3 Hour Endurance Race.
The Speedrome is the USAC's most active track with 496 events held, and also produced Tony Stewart’s maiden USAC win on August 9, 1991.
