The Cuervo 300 NASCAR O'Reilly Auto Parts Series race at Chicagoland Speedway in Joliet, Illinois, was halted shortly before its scheduled start as a sudden rainstorm moved across the 1.5‑mile speedway.
Rain Pours on the 1.5‑Mile Oval
Heavy showers drenched the track about an hour before the green flag was to wave, leaving the surface slick and requiring extensive drying efforts before any competitive action could resume.
Track officials emphasized that all lightning activity must clear the area before the cars are allowed to take the track, adding a safety-driven delay that pushed the start time back further.
Pole Position Set Amid Cancelled Qualifying
With qualifying called off on July 3, the grid was effectively set by a condensed practice session held on July 4, and Connor Zilisch emerged as the fastest driver, earning the pole position for the rescheduled event.
The cancellation of the traditional qualifying format meant teams had only a single practice run to determine starting order, a scenario that highlighted the unpredictable nature of the weekend’s weather‑impacted schedule.
Fans and competitors alike now await the moment when the rain‑soaked asphalt dries sufficiently, hoping the race can finally get underway and deliver the promised on‑track action.
Race organizers have pledged to monitor weather updates closely, ready to resume the event as soon as conditions permit, while drivers prepare for a competitive showdown once the track is cleared.
