The UMI Autocross Challenge is a highly anticipated two day motorsports event held each July at UMI Motorsports Park. Drivers from across the US and Canada spend two full days testing the limits of their machines on UMIMP’s 5/8 mi autocross course. This course features high speeds, technical sections, elevation changes and varying configurations. After the engines go silent the UMI Autocross Challenge is all about fun, friends and family. Racers get together Thursday and Friday night to enjoy the camp party atmosphere and special Friday night entertainment. There’s always something to do and plenty of food to enjoy along the way. The UMI Autocross Challenge is family friendly and makes for a great way to go racing while not having to leave the kids at home.
