The 2025 Southern Illinois 100 was the 16th stock car race of the 2025 ARCA Menards Series season, and the 45th iteration of the event. The race was held on Sunday, August 31, 2025, at the DuQuoin State Fairgrounds Racetrack in Du Quoin, Illinois, a 1-mile (1.6 km) permanent oval-shaped dirt track. The race was contested over 104 laps, extended from 100 laps due to late-race restart. In a wild race, Brenden Queen, driving for Pinnacle Racing Group, would take advantage of a late restart, and led the final 22 laps of the event to earn his sixth career ARCA Menards Series win.[5] Brent Crews, the dominant driver of the race, was involved in a late race wreck involving Alex Clubb with eight laps to go, ending his chances at sweeping both dirt races. He retired from the race and was credited with a 15th place finish. To fill out the podium, pole-sitter Lawless Alan, driving for Venturini Motorsports, and Kelly Kovski, driving for his own team, Kelly Kovski Racing, would finish 2nd and 3rd, respectively.
Background
DuQuoin State Fairgrounds Racetrack is a one-mile (1.6-km) clay oval motor racetrack in Du Quoin, Illinois, about 90 miles (140 km) southeast of St Louis, Missouri. It is a stop on the ARCA Menards Series, USAC Silver Crown Series and American Flat Track.
The DuQuoin "Magic Mile" racetrack was constructed on reclaimed stripmine land in 1946 by W.R. Hayes. The track's first national championship race was held in September 1948. In the second race on October 10, popular AAA National driving champion Ted Horn was killed in the fourth turn when a spindle on his championship car broke. The national championship race for the USAC Silver Crown dirt cars is held in his honor.
