With four races remaining in the NASCAR Cup Series regular season, Iowa Speedway will kick off the 2025 NASCAR on NBC schedule. Ryan Blaney is the defending winner of Sunday’s Cup race (Countdown to Green begins at 3 p.m. ET on USA Network).

If you’re an Xfinity fan, you already know that the series isn’t just the “middle child” of NASCAR. Nope, it’s the proving ground for future Cup stars and the breeding ground for some of the most chaotic short-track racing on the planet.

The NASCAR Xfinity Series stays in the midwest on Saturday for the HyVee Perks 250 at Iowa Speedway (4:30 p.m. ET, The CW, IMS Radio, SiriusXM NASCAR Radio). The CW App will air Xfinity Series qualifying at 12:05 p.
