Chicagoland Speedway is a 1.5 miles (2.4 km) tri-oval speedway in Joliet, Illinois, southwest of Chicago. The speedway opened in 2001 and actively hosted NASCAR racing including the NASCAR Cup Series until 2019. Until 2010, the speedway has also hosted the IndyCar Series, recording numerous close finishes including the closest finish in IndyCar history. The speedway is currently owned and operated by Nascar.

Qualifying was held on Friday, September 16, at 3:45 pm CST.^[3] Since Chicagoland Speedway is at least 1.5 miles (2.4 km) in length, the qualifying system was a single car, single lap, two round system where in the first round, everyone would set a time to determine positions 13–32. Then, the fastest 12 qualifiers would move on to the second round to determine positions 1–12.^[6]

Spencer Gallagher, driving for GMS Racing, would score the pole for the race, with a lap of 30.656, and an average speed of 176.148 mph (283.483 km/h) in the second round.^[7]
