The race was held on Sunday, June 17, 2018, in Newton, Iowa at Iowa Speedway, a 7⁄8 mile (1.4 km) permanent D-shaped oval racetrack. The race took the scheduled 250 laps to complete. At race's end, JR Motorsports driver Justin Allgaier would dominate the race to win his seventh career NASCAR Xfinity Series win and his second of the season.^[1] To fill out the podium, Christopher Bell of Joe Gibbs Racing and Daniel Hemric of Richard Childress Racing would finish second and third, respectively.

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.

Qualifying was held on Sunday, June 17, at 1:35 PM CST.^[2] Since Iowa Speedway is under 2 miles (3.2 km), the qualifying system was a multi-car system that included three rounds. The first round was 15 minutes, where every driver would be able to set a lap within the 15 minutes. Then, the second round would consist of the fastest 24 cars in Round 1, and drivers would have 10 minutes to set a lap. Round 3 consisted of the fastest 12 drivers from Round 2, and the drivers would have 5 minutes to set a time. Whoever was fastest in Round 3 would win the pole.^[4]

Austin Cindric of Team Penske would win the pole after advancing from both preliminary rounds and setting the fastest lap in Round 3, with a time of 23.971 and an average speed of 131.409 miles per hour (211.482 km/h).^[5]
