The 2026 NASCAR O'Reilly Auto Parts Series continues at Chicagoland Speedway today, Saturday, July 4th, and we've got all of the information you need ahead of the action.

Today's race, titled the Cuervo 300, is set to see the O'Reilly Series stars complete 200 laps around the 1.5-mile track in Illinois, with stage breaks on laps 45 and 90.

The race also marks the first time that the O'Reilly Series has raced at the track since 2019, with Cole Custer being the last driver to win an O'Reilly Series race at Chicagoland Speedway when he did so far Stewart-Haas Racing that year.

We can't wait to see who comes out on top this time around, and how the stars adjust to a track they are not accustomed to racing on.
