Since the inaugural event two years ago, the Cup and Xfinity series have been affected by inclement weather. After both series’ races were shortened by thunderstorms in 2023, the Cup Series ended 17 laps short of the full distance last year because of rain delays.

The NASCAR Cup and Xfinity Series are racing on the Chicago Street Course this Saturday and Sunday. The NASCAR Cup and Xfinity Series race around Grant Park in Chicago, Illinois.

The NASCAR Xfinity Series hits the streets of Chicago on Saturday for The Loop 110 (4:30 p.m. ET, The CW, MRN Radio, SiriusXM NASCAR Radio). The CW App will air Xfinity Series qualifying at 11:30 a.m.
