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 Series and Xfinity Series head to the Chicago street course for the third straight season this weekend. The Xfinity Series will practice, qualify and race in The Loop 110 on July 5, with Shane van Gisbergen in the field for the first time this year.

This year, the increasing intensity of the battle for the NASCAR playoffs takes center stage in Second City, as only four open spots for non-winners now remain on the playoff grid. One such spot was filled last week, when local hero Chase Elliott won in Atlanta to stamp his place in the playoffs and clear the way for his run at a second Cup title.
