The Indianapolis Motor Speedway, located in Speedway, Indiana (an enclave suburb of Indianapolis) in the United States, is the home of the Indianapolis 500-Mile Race and the Brickyard 400. It has existed since 1909, and is the original Speedway, the first racing facility historically to incorporate the word. With a permanent seating capacity for more than 257,000 people and infield seating that raises capacity to approximately 400,000, it is the largest and highest-capacity sporting facility in the world. Considered relatively flat by American standards, the track is a two-and-a-half-mile, nearly rectangular oval with dimensions that have remained essentially unchanged since its inception: four 1/4-mile turns, two 5/8-mile long straightaways between the fourth and first and second and third turns, and two 1/8-mile short straightaways, termed "short chutes," between the first and second, and third and fourth turns.
