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).

CONCORD N.C. - The NASCAR Cup Series returns to Iowa Speedway this weekend for 350 miles of beating and banging. Last year marked the first time that stock car racing's premier series raced on the 0.875-mile oval. For the second consecutive year, the grandstands have sold out for the main event.

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.
