Opening in July 1910, the Hamilton County Speedway is the oldest speedway in the state of Iowa. In 1938, work began on the current location at the Hamilton County Fairgrounds. The semi-banked half-mile dirt track was completed in the spring of 1939, and the first races were held on the track in September of that year.

The Hamilton County Speedway is located off US 20 at exit 140, then 1.2 miles north, then 0.5 mile east on Bank St., then 0.4 mile south on Bluff St. to the Hamilton County Fairgrounds in Webster City, Iowa. The physical address is 1200 Bluff St, Webster City, IA 50595.
