The Battlegrounds is St. Louis’ largest permanent mud run obstacle course. In addition to being a premier course, The Battlegrounds is a destination! So come out and make a day of it. Our course is spectator friendly with almost half of the obstacles within view. We offer music, activities, vendors and fun challenges throughout the festival site. Plus, there is a kids zone for the little ones, so bring out the family! (Ages 12 and under with guardian supervision) After conquering 5 miles and 30+ obstacles, you can utilize the shower facilities, stay for the party at The Battlegrounds, have a meal at Cedar Lake Cellars or sit by the lake and sip some wine (or beer!).
