Come join us for a family event where there is something for everyone.  Trucks, Snowmobiles, ATV’s, and SXS dirt drags.  We also have Mud X for heads up SXS racing around a course including mud, jumps, and some obstacles. Everyone is welcome and if you don’t have one of those, you can run in our human mud run. We race rain or shine and always have a great time!

30th Anniversary of the Interior Racing Association

Come join in the fun during our summer events  – young and old, veteran and new racers alike!

Some memories from last year:

Our mission is to provide a place to have fun as a family while participating in a sport loved by all. Interior Racing Association has been hosting family mud racing events in Delta Junction since 1992, encouraging safe and responsible racing for all ages!
