Indianapolis 500

The Indianapolis 500, also formally known as the Indianapolis 500-Mile Race, or simply the Indy 500, is an annual automobile race held at Indianapolis Motor Speedway in Speedway, Indiana, United States, an enclave suburb of Indianapolis. The event is traditionally held over Memorial Day weekend, usually the last weekend of May.

It is contested as part of the IndyCar Series, the top level of American Championship Car racing, an open-wheel, open-cockpit formula colloquially known as "Indy Car Racing". The track itself is nicknamed the "Brickyard", as the racing surface was paved in brick in the fall of 1909. One yard of brick remains exposed at the start/finish line.
