Practice session overview
The NASCAR O’Reilly Series field gathered at Chicagoland Speedway on Thursday for a mandatory practice session ahead of the scheduled race later in the weekend. Thirty‑eight drivers took to the 1.5‑mile concrete oval, using the opportunity to test aerodynamic packages and tire strategies under race‑simulation conditions.
Jesse Love emerged as the pace‑setter, posting a best lap of 31.118 seconds that translated to an average speed of 173.533 mph. His performance set the benchmark for the session and gave his team a confidence boost as they fine‑tune race trim.
Top lap times
Love’s 31.118‑second effort topped the leaderboard, followed by Jeb Burton at 31.406, Justin Allgaier at 31.424, Connor Zilisch at 31.425, and Corey Day at 31.429. The tight spread underscores the marginal differences that often define NASCAR competition.
Close behind Love, Jeb Burton secured second place with a lap of 31.406 seconds, while Justin Allgaier followed in third at 31.424 seconds. Connor Zilisch, Corey Day, and Jeremy Clements rounded out the top six, each posting times within a narrow window that highlighted the competitiveness of the field.
Race outlook
The upcoming race promises a tight battle, especially given the close practice times. With multiple drivers within a few hundredths of a second, strategy, pit stops, and late‑race cautions will be decisive factors. Series regulars such as Brandon Jones, Chase Elliott, and Austin Hill were among the drivers who used the session to gather data ahead of the event.
