This 20ft piece of fun is a dual lane course starts out by going thru tunnels and then over inflatable bars and pop ups to keep them rushing through obstacles to make it to the fnish line. Great for the smaller crowd as is or can be combined in various ways with a few of our other items to gear it toward the older participants. Check out our 45ft, 52ft and 84ft obstacle courses as well that has this piece as a part of it!!!
