U.S. Cellular 250
The U.S. Cellular 250 was a 250-lap, 218.75-mile NASCAR Xfinity Series race which was held at Iowa Speedway in Newton, Iowa every summer from 2009 to 2019. It was traditionally held in late July to early August, while U.S. Cellular was the title sponsor every year since the event's inception with different presenting companies along the way. The race was canceled in 2020 due to the COVID-19 pandemic before being removed from the schedule entirely in 2021.
