Thousands of runners will gather at MuckFest MS events in 2016 to slip, slide, slosh, climb, crawl, jump and celebrate. MuckFest MS is presented in partnership with the National MS Society.

It’s a 5K run of pure athletic hilarity, featuring a one-of-a-kind course packed with 20+ outrageous obstacles surrounded by mud-filled pits, trenches and craters. MuckFest MS attracts thousands of women and men, young and old, athletic and not-so-athletic, who band together on teams for a mucky 5K in support of a world free of multiple sclerosis.

Teams are encouraged to invite friends and family to MuckFest MS events. There’s no charge for spectators and even the little ones get their own mucky play area called Lil’ Muckers. The course is arranged so that spectators can see not only the start and finish, but also several of the most muck-tacular obstacles. After teams cross the finish line, they take their mucky mud-soaked ‘after' photo, hose off, and celebrate the day with a complimentary beer and treat in the MuckFestival area.

It’s not just about the fun and the slapstick shenanigans out on the course. There’s also a mission behind the muck: 100% of funds raised by participants benefit the National MS Society and the local chapters, which provides programs and services that help people address the challenges of living with MS and funds cutting-edge research into the cause, treatment and a cure for MS. Participants have raised over $16 million for the National MS Society.

The course layout and location was great. Much better than the he one 6 years ago. It was a super fun event and well oarganized. I ran with 2 first timers and we were already planning on next year's run half way through the course.

Awesome Mud Run

Aug 10, 2016 by Ali

This is the most fun I have ever had at a race. Everyone was so excited to be there: the runners, volunteers, and other organizers. The MC is amazing, he was hilarious and very engaging, and the "walk on water" challenge was my favorite. Anyone can do the race; the obstacles provide some challenge but are not super difficult, and if you need to you can skip an obstacle. Many people with MS participate and are mailed blue bandanas prior to the event. The free food afterwards (burgers, hot dogs, veggie wraps, etc) and free beer were awesome. Overall the event is very well organized and is a blast! I can't wait to go again next year!

Great Time

Jun 25, 2016 by Danielle DiNapoli

First ever to try a mud run and the idea of people helping strangers through the obstacles was incredible and made this less intimidating for all virgins. The MC was extremely personable and got each and every heat excited. While the obstacles were not easy, they were not ridiculous, they were absolutely fun. My only complaint is about the people who drop their papers/numbers, bottles, clothes etc and don't pick them up. It's a charity event where volunteers are going to have to and it involves mud, people....have some respect! Otherwise the event was awesome and well organized, the volunteers were friendly and energetic, and it was for a great cause. How could there be complaints? Mud, "pools", climbing things, and places to run around...then drinks???? An adult playground=paradise!!! Excellent job to everyone there today working and running.

Out of all the ones I did...This one was the best.

Muckfest MS

Dec 27, 2015 by Colleen Toussaint

This was my teams 2nd year in participating at Muckfest and we had a fabulous time.. The announcer makes the beginning so much fun. The obstacles are fun with a little challenge, perfect for some that do not run or workout on a regular basis. Everyone can complete this course!
Our teams start time was in the middle and some of the obstacles no longer had watery mud. So to slither through a tunnel that is tried up was not so much fun. Make sure there is plenty of wet mud at every obstacle. If the last obstacle has lots of mud, not only will it be more fun, it will make for a great end of the race team photo.
We've participated in many walks and there is always good free food at the end so it is surprising after this ms event there is just a bag of chips. At least make sure people are aware to bring money or bring their own lunch.
It is a very organized event and we look forward to 2016; however with the event in November instead of October we are concerned that it might be a little cool to be jumping into the water.

Awesome Event

Jun 28, 2014 by Bill

Awesome event. Good obstacles. Nice base setup.

-Obstacles were good (as they have been for the last few years)
-Signature obstacles like the swings make this race special! Keep them!
-MUCH better MC this year. While your chapter president (used in previous years) is important and provides good info on MS, she is not very enthusiastic.
-Why shorten it to a 5k? 5 miles was awesome and you have the space for it @ Ellis Preserve. Also - maybe try a cloverleaf patter instead of a big loop so spectators can see the good obstacles.
-Please bring back better food at the end or get rid of it completely. A bag of chips is NOT acceptable. The beer was appreciated.
-Solid location - nice terrain and good hills. However - if you have a race to raise money for MS, PLEASE have some SHADE for spectators. You know better than anyone why that is important.
-Extremely well organized. Your event coordinator is meticulous and extremely thorough. This event did not suffer from any of the usual issues (check-in, bag storage, parking etc...)

For the detractors in other reviews - the obstacles (with video) were posted on the website. This event isn't marketed as a Tough Mudder or Spartan Run so don't expect barb wire, fire, or electric fences. This is a fantastic run for everyone, but if you want the "extreme" obstacles try another race.

This was my second year participating and much worse than last year. I was disappointed by the reduction of miles, but thought it would still be fun. It was not. The obstacles were spread too far apart and I waited for 20 minutes for one obstacle when the decision was made by my teammates to skip b/c our muscles were tightening. At the end, we were looking forward to some solid, good food and were provided junk. Really? You went into get a beer and couldn't leave until you finished.. however, the "free food" aka junk snacks were outside of this area.. and oh how convenient, let's sell food. Our team didn't bring money to the event based on our experience from last year having food. Really disappointed and will not be participating next year. We'll find another MS run to raise our donations.

Course was to short.1 drink and no food.I was in 3:30 heat,everything was gone.What happened to the sandwiches?Less obstacles,your running out of land for this event.

Put it back to 5 miles...where's the burgers?

Apr 28, 2014 by kyle john love

By shortening the run to a 5k with nearly the same amount of obstacles, you created long back up lines at each obstacle, ruining the continuity of the run. The run should be 5 miles like the first year. The most important thing about this event is raising money for the cause, but there are people out there, like my group who not only do it bc we have family members with MS, but also because we like the physical challenge. Also, this year with a late registration, we paid 75 a piece instead of 55. And for that we got less for more. The donation aspect is great and that's why we're here, but if in the span of one year you shorten the race, provide less obstacles, and give us a soggy banana instead of a burger and fries, that by that point we're dying for, you are going to lose participants. You had to expand to a second day this year based on growing numbers of entrees, that's because the challenge, and the perks of hot yummy food at the end were worth suffering for a good cause. let's go people muck yea.
