Located at the Marion County Fairgrounds in Knoxville, Iowa, USA, this half-mile dirt oval raceway is revered as the 'Sprint Car Capital of the World'. Every August the Knoxville Nationals, the paramount sprint car event in the United States, is held at Knoxville Raceway. The event takes place over two days and now features a nearly one-million-dollar prize purse. The track was originally built in the late 1800s as a horse racing venue and has progressed from racing stock cars to modifieds to supermodifieds to its current sprint cars.
