Iowa Speedway, the track where the race was held.

Iowa Speedway is a 7/8-mile (1.4 km) paved oval motor racing track in Newton, Iowa, United States, approximately 30 miles (48 km) east of Des Moines. The track was designed with influence from Rusty Wallace and patterned after Richmond Raceway, a short track where Wallace was very successful. It has over 25,000 permanent seats as well as a unique multi-tiered Recreational Vehicle viewing area along the backstretch. The track hosts the NTT IndyCar Series and NASCAR events.

After the 2020 race was canceled due to the pandemic, the race was removed from the 2021 schedule. In 2024, it was announced that the Xfinity Series would return to Iowa with a Cup Series race.
