After cancelling the race with less than 24 hrs notice and several people driving quite a distance from the actual supposed race site to pick up packets that were not there (that’s where we first learned about the cancellation), I asked for a refund. I was denied a refund saying that it stated during registration that it was a no refund event. The only thing it said about refunds was that it would not be refunded if cancelled due to weather. This cancellation was due to poor planning and not getting required permits for city ordinance, not weather. Needless to say, we will not be signing up for this race in the future.

Very disappointed that the race was cancelled less than 24 hours before start time, with no reasoning

Great race with fun obstacles and LOTS of chances of get down and dirty in the mud :)


Not the best,but good for first timers.

I did not have high hopes going into this race due to other reviews, but it wasn't horrible. The obstacles were well built and self explanatory. The mini monkey race was a lot of fun for my kiddo. The most disappointing part was that they nickel and dime you to death. 20 to have someone "park" us and then having to pay 5 dollars for a bib because I couldn't drive 2 hours to get it the night before? Rip off. And even though this is billed as a mud run it most definitely wasn't. There were two "mud pits". If this is your first OCR it may be worth it. For the OCR vets I still say Rugged Maniac is the best race out there.

People shit on this brand but I really don't get it. 15 or 20 online, then 30 dollars in fees on race day(only 10 more than spartan or savage). For that price I dont expect chip timing, free photos, or free beer, just a fun time. The obstacle spread was decent with plenty of rigs and Walls. Bottle necking sucked but you're not being timed so just be a decent human and have some patience. Also, there is nothing stopping you from running all day. Hopping in the start corral is simple those unattendive volunteers all of a sudden become a plus. If you want to be a pro ocr racer or look like one onFacebook, you probably hate terrain. if you are just looking for a simple but fun course for a decent price, sign up. Its "free"

Not even worth the $15 is right!!! Besides the total lack of parking with long drive lines, the race organization is terrible. Tone of walkers and long lines at obstacles were disappointing. No real post-race treats and cheap shirts. Only 2 wash off hoses for 13,500 racers... WHAT?! Most concerning was running right past a Fracking site, watching a worker less than 20 yards away in a full haz-mat suit. Did I poison myself while attending a less than mediocre walking event? Will NOT do this race again.


Where were the obstacles?!

Aug 26, 2019 by Justin Esteves

Never doing terrain race again. Very disorganized, no one taking pictures of you when your at obstacles! No free beer at end of race! They nickel and dime you the whole time. There are way better ones worth the price. Rugged Maniac, Tough mudder, spartan race offer mich more even when you get discounted tickets. They usually have free fruit and sports drinks for when you finish. Terrain race offered water and wanted you to pay for everything else. PLEASE NEVER SIGN UP FOR THIS RACE!!

Free?! This race ended up costing me way more than it was worth. It was a boring race with little to no challenge. Obstacle attendants on their phones. 2 mud “obstacles”. No free finishers beer. 5$ packet pick up is literally having a person hand you your bib. No swag bags. WHITE T-shirt’s. Worse than the run is the customer service. It doesn’t exist. I had numerous questions about switching wave time, transferring registration and under 18 waivers and was bounced around from fb to email with little to no help. They don’t even have a phone number to call. I called the event company Active and they told me that in order to transfer my husbands “free” reg to my minor child it would cost me 65$. I didn’t do anything from there and took my chances. The reg attendant didn’t even ask for a under 18 waiver. They are useless. Will never run a terrain race again and would never recommend.

It seems I'm not the only one who was very disappointed in this race. I love obstacle races and am easily pleased, but this was a joke. In addition to all the secret hidden fees which have been already mentioned, the race was very poorly organized. Parts of the race were not marked and crossed through areas where people and cars were wandering through, leaving us unsure where to go. Huge bottlenecks at every obstacle. Most of the obstacles were poorly put together, like the "crisscrossed bungee cord" obstacle where half the cords had fallen down, or were just stupid, like "stop and flip a tire before you go on." Very few legitimate obstacles, very poor organization, very overpriced with hidden fees for a "free" race. Total scam, absolutely do not recommend.

Worst mud run ever. Was drawn in by the *free* registration that was not in fact free after paying required insurance and online fees. Packet pickup ended up being an hour away from the event, and hour farther than where I lived...so ended up paying an additional $20 day of to pick up 4 bibs (that was the "packet") at the event. Had to pay $20 to park which was extremely disorganized. Then, they charged $5 to check a bag! The obstacles were a joke...there was not the 20+ mentioned on the website unless you count climbing a hill and trying not to break your ankle tripping in holes or on blackberry vines. They had 2 sets of walls that we waiting at for 15 minutes each. Huge bottleneck. I'm pretty sure we waded through a pond of horse manure as well. And we never got an ice cold drink at the finish...unless they are talking about the dixie cup of water.
Definitely will never register for another Terrain Race. There are far better, better organized events out there.
