A. J. Allmendinger started on pole and remained in the lead until Stage 1, where he won the stage. Justin Allgaier had locked up the brakes in turn 1 in the gravel, but kept his car away from the tire barrier. The team had to make lengthy repairs to the vehicle. Cole Custer's car took some damage after he mowed down some banners, and Chase Briscoe took the stage 2 win when the leaders pitted.

Brandon Jones, who had to start the race at the rear in a backup car, blew a tire and damaged his right front. With 2 laps left, Gray Gaulding lost his brakes and spun out of control in the gravel. His rear-end got damaged, but track officials towed him out and his team made repairs to return to the race. Matt DiBenedetto (who led the most laps) lost control on the final turn while running second and ultimately finished one lap down. Christopher Bell (who struggled with handling issues during Stage 1) took the lead and managed to hold off Austin Cindric (who weaved his way through from 20th to second) to win the race.
