Huge rip off, don't waste your money.
$65 tickets for a mud run with only 1 mud obstacle. The over hyped water slide at the end was a tarp down a shallow hill with not enough water on it. $10 parking and $10 per spectator. Terrible event, not worth it at all.


Rip Off

Jun 03, 2015 by Julius

I paid for myself and my son to run this. We were looking forward to it. The run was scheduled for Sunday in Fairbanks, AK. I get an email the Tuesday saying that the run was canceled due to logistics. I emailed customer service to see about getting a refund since they canceled the event. I was told that they did not offer refunds and that I was more than welcome to run the event 500 miles away in Anchorage. This company offered an event and then they stole everyone's money that signed up. I understand that stuff happens, especially getting things to interior Alaska, but that is not a reason to flat out steal your customers money that wanted to do your event. NEVER sign up for an event by Mud Factor or offered by Eight51, Inc. They are thieves and do not care about there customers.

WORST 5K EVER!!!!!! There was multiple problems with this race
1. Only 1 actual mud obstacle! I thought this was a MUD run?
2.$10 for parking and a spectator fee! I have done multiple 5ks and I have never heard of a spectator fee! such a rip off!
3. I signed up a couple weeks before the event and paid $65 but then on the day of the event the price was cheaper at $45! RIDICULOUS!!

I will NEVER be participating in another run that Mud Factor hosts!


Amateur mud run, lots of room for improvement

Mar 22, 2015 by Cameron

This was only my second mud run, but compared to the other run, this was run pretty poorly. I actually thought maybe this was the first MF run in Sacramento, but in reading reviews I see this is probably just how they do things

Biggest gripe: Amusement park like lines for obstacles. We waited 20+ minutes in a slow moving line for the barbed-wire crawl.

The obstacles were reasonably challenging, and seemed safe enough, however they were all a little too packed with runners. We waited too long at too many of them. The mud under the barbed wire crawl had A LOT of 1" gravel in it, more like crawling through wet concrete. I don't mind a little pain, but it slowed a lot of people up, and left me with cuts on both knees and one elbow.

There was a rinse station, but again it only fit about five people at a time and there were always at least 100 people in line for it.

There was only one food cart, zero beer, and zero fun sponsor tents or swag giveaways. Checking in was intuitive, but they didn't give or have any information on gear check or even the start line. We figured it out because there were so few tents to choose from :-/

I thought the DJ starting the waves was decent and he had high energy. There was plenty of mud and some short hills in the course that we liked and we got plenty dirty, so the DJ and the mud bump this event to two stars.


Disappointed, felt cheated. HORRIBLE RUN.

I don't even see how they can call this a mud run. It forces me to select 1 star, otherwise, I'd pick zero.

1. I signed up a little earlier in the year a long way out from the event. Hoping to save money, as this run like ever race or mud run shows the price will increase closer to the event. BUT, then they ran sale after sale after sale later on, closer to the event, So if I had just waited, I would have got a better deal. Made no sense.

2. The parking was a nightmare and $10. Such a joke. And this wasn't clear to find on the website.

3.There attitude towards runners, Ya know, THEIR CUSTOMERS was AWFUL. They clearly care about one thing, making money. Not about providing a fun running event for families and friends to attend. When my friends and I tried to let the company know about the issues on their Facebook page, they just made rude outrageous comments and blocked commenters. NOT THE WAY TO TREAT YOUR CUSTOMERS. Basically if any one has a real review or thought on their events and puts it on their Facebook, they block them. WEAK!

4. OBSTACLES ARE A JOKE! Nothing unique at all, but more importantly they weren't even near safe. made by some idiots. I don't know a lot about building things, but all other runs I've done had way better and more sturdy structures.

PLEASE DO NOT WASTE YOUR MONEY AND DON'T SUPPORT THESE PEOPLE!


COMPLETE RIP OFF!! DO NOT DO IT!!!!!!!!!

Jan 20, 2015 by Jimmy Standges

WORST RACE EVER!! unsafe. Total Rip off!!!!! This race is GARBAGE!! Sign up for a local run event, will be more worth you time. If I could rate it Negative stars, I WOULD! Nothing they promised was actually provided. This is essentially a Ponzi scheme. They just run sale after sale, trick people into sign up and then provide a garbage event. Thieves.

2 x Mud Factor Runner, Good Entry Level Race

Nov 16, 2014 by Chad Rutt

I ran this race in San Bernadeno in 2012 and 1013 and am signing up now for 2015. It's a great entry level race, that has gotten better as the years go by. I am excited to see what 2015 will bring. It caters to first time racers and novices. Get in a early wave if you are a seasoned Mud Runner. I like this course because it has some unique obstacles, challenging course with minor hills and a great workout.


Will not be doing this again (Kids Run)

Nov 10, 2014 by Selena

If I could give this negative stars I would.First, the parking charge of $10 was not "all over the website" like the attendant said it was, which she then corrected to "when you register". We had to drive 2 separate cars so paying $20 for parking didn't make any sense and we parked my husbands car across the road from the grove, well off the road which was in front of an orchard, where a handful of other cars were parked. When we came back to the attendant, all in one car, she then threatened us that his car would be towed. We decided to go ahead and kids settled, but it was completely disorganized (something I've seen over and over again in other reviews) we were bounced back and forth between booths (even though we had preregistered) because they couldn't find our information and when I asked for further directions once we were finally in the arena, I was told to go back to the registration booth. Once I told that lady they sent us there for instructions, she said "Oh. Well check with the DJ". The DJ was the only helpful person there. My husband at this point went back to his car to make sure it wasn't towed and ended up missing our kids run. Not that it was a real run anyway, it was missing obstacles that were pictured and featured in the video and they were done in literally 5 minutes.
My husband spoke with some of the other people who were waiting with their vehicles who had also been threatened with being towed and a grandfather who had gone to see his grand kids said he asked for the parking attendants managers information (she was extremely rude to him as well) and she refused to provide it. I will definitely not being attending this ever again and will be telling everyone who asks how this weekend went they should look to a competing company if they want to do something like this. You guys suck.


Worse mud run ever

Aug 13, 2014 by Natalie Z.

I don't even see how they can call this a mud run. There was a mud puddle, and then one mud pit at the very end of the run so they can take pictures and say its a mud run. Everything was cheap quality but they wanted high dollar for everything. I have been to several mud runs, this was just a run and it was AWFUL. The hosts were swearing on loud speaker with children present, and there were no garbage's! I will never return and neither will my five other friends that went. HUGE disappointment. WASTE OF MONEY!!
