14th Annual Mudder's Day Madness Mud Run 5K & Fun Run 2026

Keeping with tradition, Harmony's 14th annual Mudder's Day Madness Mud Run is the Saturday before Mother’s Day, May 9th, 2026. During our traditional 5K, the course spans across Montvale’s muddiest trails with 20 obstacles. From Adversity Hill to the Tire Traverse to the A-Frame Climb, 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 also 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! Early bird pricing ends after February 28th, so register today!

Medals will be presented for fastest 3 male & 3 female 18+ overall, and for the fastest 3 male & 3 female 17 and under overall only. 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. We'd like to give a huge thank you to Peaceful Side Brewery for sponsoring our beer tent again this year!

Funds raised from this event will support Harmony’s therapeutic programming at Camp Montvale which includes our equine therapy program and therapeutic camps for foster and adoptive children and families.

REGISTRATION

Online registration is available through May 3, 2026. Guaranteed shirt cut-off is April 2nd! Shirts and bibs must be picked up in advance of the race. Participants who registered after April 2nd will have first come first serve shirt options at packet pickup. 

If space allows, we will reopen the event for registrations during the week of the race. Once the race is at capacity, we will close registration. Therefore, REGISTRATION ON THE DAY OF THE EVENT IS LIKELY NOT AN OPTION AND SHOULD NOT BE COUNTED ON.

WINDOWED START TIME FOR 5K

The race will have windowed start time corrals: 10:00-10:30, 10:30-11:00, and 11:00-11:30. You may cross the start line at any time during your chosen time window! You must select your windowed corral when you register. Each corral is capped at a predetermined number of registrants. If the window you prefer is full, choose any open window and then contact us at connect@harmonyfamilycenter.org to make the correction. Teams should choose a window prior to registration and share with all team members for their registration. Any team or individual interested in competing should place themselves at the beginning of whatever window chosen to avoid as much congestion as possible. We recommend all participants who intend on walking the course select the first window, as all participants still on the course at 12:30pm will be picked up by race personnel.
