The Brickyard 400 was an annual NASCAR Cup Series points race held at the Indianapolis Motor Speedway in Speedway, Indiana. The inaugural race was held in 1994 and was the first race other than the Indianapolis 500 to be held at the Indianapolis Motor Speedway since 1916. In its inaugural running, the Brickyard 400 became NASCAR's most-attended event, drawing an estimated crowd of more than 250,000 spectators. The race also paid one of NASCAR's highest purses. From 1994 to 2020, the race was held on the 2.5-mile oval, for a distance of 400 miles. The race was dropped in 2021 in favor of the Verizon 200 at the Brickyard which is run on a combined road course and run a distance of . The term "Brickyard" is a reference to the nickname historically used for the Indianapolis Motor Speedway. When the race course opened in August 1909, the track surface was crushed stone and tar. That poor surface was the cause of numerous and sometimes fatal accidents, so the track was subsequently repaved with 3.2 million bricks. Over time the bricks were paved over with asphalt, and now only a one-yard strip of bricks at the start/finish line remains exposed. From 1994 to 2017, the event was held on the first weekend of August, or the last weekend of July. For 2018 and 2019, after schedule realignments, NASCAR moved the race from its traditional summer date to be the last race of the regular season on the weekend after Labor Day. In 2020 only, it was held on Independence Day weekend. In 2021, the event was moved back to late-July/early-August and moved to the Grand Prix road course rather than the full oval. The layout utilized is the newer, modified layout of the circuit previously used for the Formula One U.S. Grand Prix, and currently used for the IndyCar GMR Grand Prix. From 2005 to 2009, the race was known as the Allstate 400 at the Brickyard under a naming rights arrangement with Allstate. From 2012 to 2016, Crown Royal was the title sponsor of the race; under its sponsorship, the race honored a military member or first responder selected by fans, who received VIP tickets to the event, and their name included in the title of the race.
