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".^[1] 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 expanded to that of being an endurance race and is one of the major endurance races on the IMSA schedule, joining Daytona, Sebring, Watkins Glen, and Petit Le Mans.^[2] The race stayed as a 6 Hour race in 2025, but is set to revert to being a 2 hours, 40 minute race in 2026 and will be replaced as a 6 hour Endurance Cup race by the IMSA SportsCar Weekend at Road America.
