Keeping with tradition, Harmony's 12th annual Mudder's Day Madness Mud Run is the Saturday before Mother’s Day, May 11th, 2023. In addition to our traditional 5K, there is also an optional 10K course with six more obstacles for only the toughest competitors to attempt. The course spans across Montvale’s muddiest trails with close to 30 obstacles. From Adversity Hill to the Tire Traverse and the A-Frame Climb to the Big Ol’ Hill, runners from ages 8 and up can race on their own or with a team. Costumes are encouraged and celebrated! Medals will be presented for fastest male/female completions by age, largest team, best costumes, and more! Vendors, food trucks, refreshments, and music will be onsite for all to enjoy. The annual Mudder’s Day Mud Run is Harmony’s premier event supporting family programs and therapeutic services so all may live their best lives.
