The first race was scheduled for September 16, 1922, but rain delayed the race until the following day. More than 50,000 people attended the first of only four auto races that would ever be held at the Kansas City Speedway, which also hosted motorcycle racing. Notable attendees at the first race included the Mayor of Kansas City, Missouri Governor Arthur Hyde, and great race car drivers, including Ray Harroun, and Barney Oldfield. Seventeen drivers participated in the first race, including Tommy Milton, Leon Duray, Tony Gulotta, and Cliff Durant. The race was won by Tommy Milton, who was also the first driver to win the Indianapolis 500 twice. The first race also saw the only fatality at the track when the race claimed the life of 27-year-old Roscoe Sarles who collided with Pete Depaola on the 110th lap. The average speed for the first race was 107 mph, which was significantly faster than Indianapolis 500 races of that time. In fact, the average speed at Indianapolis did not exceed 100 mph until 1925.
