After hosting a virtual event in 2020, we are THRILLED to return to Montvale for the 9th Annual Mudder’s Day Madness 5K Mud Run. Typically hosted on Mother's Day weekend, we have rescheduled to October 23, 2021, to ensure a fun and safe event. This exciting 5K takes runners through Montvale's beautiful property while getting muddy on 18 obstacles including a muddy slide, a sludgy army crawl, and a jump in the lake. Proceeds benefit the work of Harmony Family Center at historic Camp Montvale to ensure that this special place remains a space for connection and restoration for years to come. Learn more about Harmony Family Center at Montvale by visiting the website.
