The NASCAR Cup Series resumes this weekend as the field prepares for the Iowa Corn 350 at Iowa Speedway. This race marks the 23rd points-paying event of the 2026 season and signals the start of the final push toward the playoffs. Defending winner William Byron returns to the track looking to secure his position in the standings during this critical regular-season stretch.
A total of 36 cars appear on the official entry list for Sunday's event. The field includes the primary contenders from top teams such as Hendrick Motorsports, Joe Gibbs Racing, and Team Penske. Teams have finalized their crew chief assignments and sponsorship packages for this stop in the Midwest.
Fans can catch the race broadcast starting at 3:30 p.m. ET. The event is available on USA Network and the HBO Max platform. Those who prefer audio coverage can tune in via the Motor Racing Network or SiriusXM NASCAR Radio. With limited races remaining before the postseason cutoff, every position on the track carries weight.
This visit to Iowa Speedway represents a key date on the calendar for drivers fighting for their spot in the final playoff field. The combination of the track configuration and the high stakes of late-season racing usually produces significant movement in the standings. Teams will complete their final inspections before green flag conditions arrive on Sunday afternoon.
