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 Xfinity Series returns to the streets of Chicago for The Loop 110 (4:30 p.m. ET, The CW, PRN Radio, SiriusXM NASCAR Radio), kicking off a two-week stretch of road-course tests for the series.

The NASCAR Xfinity Series season continues with the Focused Health 250 at Atlanta. See Friday's starting lineup here.
