About the race
Mudder’s Day Madness Mud Run is a family-friendly obstacle 5K held at Montvale in Maryville, Tennessee, May 9, 2026—the day before Mother's Day. The course features trails on a marked 5K route, more than twenty obstacles—including Adversity Hill, Tire Traverse, and the A-Frame Climb—and a lake dip. Runners aged 8 and up can compete solo or as a team; costumes are encouraged with awards for creativity.
A Fun Run for 4+ year-olds follows the 5K, offering a shorter route with several obstacles. The event also hosts vendors, music, and refreshments, with proceeds supporting Harmony Family Center’s therapeutic programming at Camp Montvale (equine therapy and camps for foster/adoptive families).
