They stipulated that the vehicle would have to maintain an average speed of more than 5 miles per hour (8.0 km / h) over a 200 - mile (320 km) course . The offer led to the first city to city automobile race in the United States, starting on 16 July 1878 in Green Bay, Wisconsin, and ending in Madison, via Appleton, Oshkosh, Waupun, Watertown, Fort Atkinson, and Janesville . While seven vehicles were registered, only two started to compete: the entries from Green Bay and Oshkosh . The vehicle from Green Bay was faster, but broke down before completing the race .
