JR&CO 150

ARCA Menards Series race at Iowa Speedway in Newton, Iowa, scheduled for 150 laps on the 0.875-mile paved oval. Title sponsor JR&CO is a commercial roofing contractor, established 1986. The 2026 running was held Friday August 7 as the opening race of the Iowa NASCAR weekend. The Mercury network does not currently run an ARCA beat, so this entity exists to hold the race identity and its mark rather than to anchor coverage.
