IMSA Battle on the Bricks

The Tirerack.com Battle on the Bricks is an IMSA WeatherTech SportsCar Championship event held on the combined road course at Indianapolis Motor Speedway in Speedway, Indiana.

The original version of the race, held from 2012 to 2014, was a support race for the Brickyard 400, as part of "Kroger Super Weekend at the Brickyard". In its first two years, it was held as part of the Grand Am Rolex Sports Car Series, and moved to the United SportsCar Championship in 2014. The race went on hiatus after 2014.

The race was revived in 2023, as part of the WeatherTech SportsCar Championship. It is now held as a stand-alone event held in September. For 2023, the race was a 2 hours, 40 minute length. For 2024, the race will expand to an endurance race and be one of the major endurance races on the IMSA schedule, joining Daytona, Sebring, Watkins Glen, and Petit Le Mans.

Support races
The Brickyard Sports Car Challenge is a sports car race in the IMSA Michelin Pilot Challenge series (formerly the Continental Tire Sports Car Challenge), with two classes being run concurrently. It was held as support to the Brickyard Grand Prix, which was in turn a support race to the Brickyard 400. The 2023 revival will be one of IMSA's major races, as a four-hour race.
