The Indianapolis Motor Speedway is the world's largest spectator sporting facility. It plays host annually to three events in three major racing series: Indianapolis 500 Mile Race (IZOD IndyCar Series), Brickyard 400 (NASCAR Sprint Cup Series) and Red Bull Indianapolis GP (MotoGP World Championship). The Indianapolis 500 and Brickyard 400 take place on the 2.5-mile oval, while the Red Bull Indianapolis GP is contested on the 16-turn, 2.621-mile road course.
Established in 1909, the Indianapolis Motor Speedway has long prevailed as an icon of motorsports excellence. Beginning in 2009, the Speedway celebrated its Centennial Era, commemorating the 100th anniversary of the facility in 2009 and the 100th anniversary of the Indianapolis 500 Mile Race in 2011.
This celebration of two important milestones spanned three years and included several unique and historical events. Visitors to the Speedway during the Centennial Era saw not only a focus on its rich history, but a strong emphasis on looking ahead to the future.
