Talladega Superspeedway is a motorsports complex located in Eastaboga, Alabama, United States. It was constructed in the 1960s in place of the abandoned Anniston Army Airfield by International Speedway Corporation, a business controlled by NASCAR's founding France family along with Daytona International Speedway and several other racetracks. At 2.66 miles (4.28 km) long, Talladega is the largest (and most steeply banked) oval track in the Sprint Cup Series and has seating provisions for over 175,000 patrons.
