open-wheel racing featuring the IndyCar Series and the Firestone Indy Lights, as well as a driver question period and autograph sessions, music and other attractions. The series again left after the 2015 season, and the track hosted no major professional races until ARCA returned in 2021. Dirt track history The track was a private horse racing track by 1876. In 1891, the site was purchased by the Agricultural Society of the State of Wisconsin to create a permanent site for the Wisconsin State Fair (which it still is). The first motorsports event was held on September 11, 1903. William Jones of Chicago won a five lap speed contest, and set the first track record with a 72-second, lap. There were 24-hour endurance races in 1907 and 1908. Louis Disbrow won the first event in 1915, averaging . Barney Oldfield's success at the Mile helped make him a legend. He set the track record in 1905 and raised his speed in 1910 to in his "Blitzen Benz". In 1911, Ralph DePalma won the first Milwaukee Mile Championship car race, four years before his Indianapolis 500 win. Oldfield drove a gold car built by Harry Miller that completely enclosed the driver (called the "Golden Submarine"), and in June 1917, he beat DePalma in a series of 10 to match races.

Huge new grandstands were installed in the 1930s, with seating for 14,900 people. They replaced the original grandstands that had been built in 1914. A roof was placed over the grandstands in 1938. These grandstands stood until new aluminum grandstands were installed in September 2002. The 1939 race was the first AAA Championship race. The 1937 non-championship AAA event was best known for running 96 laps (instead of 100) due to a scoring error. It was won by Rex Mays, who continued his domination throughout the 1940s by winning in 1941 and the next race (after World War II) in 1946. The tradition of hosting the "race after the Indianapolis 500" began in 1947. In the 1969 film, Winning, the character Frank Capue, played by actor and part-time race car driver Paul Newman, remarks, “Everybody goes to Milwaukee after Indy.” The Milwaukee Mile held more national championship midget, stock, and
