The Mud Run involves a mud pit dug to a specific depth and length in which a vehicle attempts to power through and reach the other side in the shortest time possible. Heavy equipment will be standing by to pull out those that get stuck before reaching the end. There are typically several different classes of vehicles to keep competition fair. We will have two different mud pit depths and three different classes, based on tire size, Hayden of Kansas Ram Club said. The vehicles need to be registered and street legal, with the exceptions of a few minor modifications. The intent is to allow the average person to be able to come out and have fun! We we have trophies and door prizes in all classes. The mud run is organized by the Kansas Ram Club at the Bourbon County Fairgrounds.
