What is The Battlegrounds?

The Battlegrounds is St. Louis' largest permanent mud run obstacle course. Our 30+ military-inspired obstacles are built on a large scale to test the endurance and mental toughness of even the fittest athlete all while supporting a local charity. 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 free 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!)
