NASCAR Iowa 2025: Start Time, TV, Streaming, Lineup for Iowa Corn 350

The NASCAR Cup Series is heating up as we approach the playoff seeding. This week’s event at Iowa Speedway is just four races away from the start of the 10-race postseason at Darlington Raceway. Bubba Wallace punched his ticket to the playoffs by winning the Brickyard 400 at Indianapolis Motor Speedway, holding off Kyle Larson on the final restart in overtime.

Ty Gibbs secured a victory, finishing 21st, to win NASCAR’s inaugural in-season challenge last week. Now, the action shifts to Iowa Speedway, a unique short track oval with low banking. Despite being relatively new to the NASCAR Cup Series calendar, it’s being compared to the Richmond Raceway.

With just four races to go before the playoffs, 13 of the 16 playoff spots have been clinched. The Iowa Corn 350 powered by Ethanol is set to take place on Sunday, Aug. 3, at 3:30 p.m. ET on Iowa Speedway. This race will be broadcast on USA Network, with pre-race coverage beginning at 3 p.m. ET. Plus, you can catch a live stream of the event on Peacock. Stay tuned for more thrilling NASCAR action as the playoff picture continues to take shape.
