Missouri State Fair Speedway is a half-mile (.805 km) dirt oval race track located at the Missouri State Fair grounds in Sedalia, Missouri. The track was built along with the fairgrounds in 1901 as a one-mile (1.6-km) horse racing track. The first auto races were held in 1914 and 1915. Cars returned from 1935 until 1941, and again from 1946 until 1985 and 1989 until the mile was abandoned in 1998.{{cite web|title=Missouri State Fair Speedway |url=http://www.na-motorsports.com/Tracks/MO/StateFair.html |work=North American Motorsports Pages |access-date=15 July 2011 |archive-url=https://web.archive.org/web/20111114104657/http://na-motorsports.com/Tracks/MO/StateFair.html |archive-date=14 November 2011 |url-status=live }} One USAC National Championship race was held on the mile in 1970, won by Al Unser.{{cite web|title=1970 Sedalia 100 |url=http://www.champcarstats.com/races/197015.htm |work=Champ Car Stats |access-date=15 July 2011 |archive-url=https://web.archive.org/web/20120905120458/http://www.champcarstats.com/races/197015.htm |archive-date=5 September 2012 |url-status=live }}
