Keeping with tradition, Harmony's 13th annual Mudder's Day Madness Mud Run is the Saturday before Mother’s Day, May 10th, 2025. During our traditional 5K, the course spans across Montvale’s muddiest trails with over 30 obstacles, some of which are brand new this year. 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! In addition to our 5K, we now have a family friendly, untimed Fun Run for anyone ages 4 and up! The Fun Run distance is about 1.2 miles and will include trail running, field running, obstacles, and mud, of course!
Medals will be presented for fastest male/female overall and 1st place completions by age for male/female. Trophies will be awarded to the largest team, best team costumes, and fastest team! All participants will get swag and a participation pin! Vendors, food trucks, refreshments, and music will be onsite for all to enjoy. A big thank you to our Beer Tent Sponsor- Peaceful Side Brewery in Maryville for supplying the alcoholic refreshments for the event!
