After winding through Wine Country at Sonoma Raceway, the NASCAR O’Reilly Auto Parts Series heads to Chicagoland Speedway for the first time since 2019 on Saturday (5:30 p.m. ET, The CW, MRN Radio, SiriusXM NASCAR Radio).
The race will be the 20th points-paying event of the 2026 O’Reilly season.
This will be the O’Reilly Auto Parts Series’ first time back in Joliet, Illinois since 2019 and will be a bit of a homecoming for points leader Justin Allgaier who is 207 markers ahead of Jesse Love in the standings.
Cup Series mainstays Connor Zilisch (No. 1 JR Motorsports), Chase Elliott (No. 88 JR Motorsports) and Cole Custer (No. 0 SS-Greenlight Racing) help make up the 38 cars entered in this weekend’s event. Custer is also the most recent winner at Chicagoland.
