The Iowa Speedway is slated to host a three‑day NASCAR weekend in August 2026, featuring the ARCA Menards Series, the NASCAR O’Reilly Auto Parts Series and the Cup Series. The schedule kicks off on Friday, August 7, with the ARCA JR&CO 150, continues on Saturday, August 8, with Xfinity Series qualifying and practice, and culminates on Sunday, August 9, with the Cup Series’ Iowa Corn 350 Powered by Ethanol.
Friday’s Stormy Kickoff
Friday’s forecast calls for a 54 percent chance of afternoon thunderstorms, a factor that could influence track conditions and race strategy for the ARCA event, which is set to begin at 7:00 p.m. Eastern and will be televised on FS1.
Saturday’s weather outlook is markedly clearer, with only a 21 percent chance of rain and mostly sunny skies, allowing teams to complete practice and qualifying sessions for the O’Reilly Auto Parts Series without major interruptions; coverage will be carried on The CW.
Sunday’s Cup Finale
Sunday’s centerpiece, the Iowa Corn 350 Powered by Ethanol, will see its Cup Series qualifying take place at 3:30 p.m. Eastern, also on USA Network, while the race itself promises high‑stakes competition under what should be predominantly dry conditions.
In addition to the broadcast partners, the weekend’s audio feed will be available through MRN and SiriusXM NASCAR Radio, and fans can stream the Cup Series finale on HBO Max, ensuring multiple platforms for viewers across the United States.
Overall, the August weekend at Iowa Speedway blends high‑octane racing with a weather narrative that could reshape the competitive dynamics, making it a must‑watch event for NASCAR enthusiasts.
