Overall I had a great time. This was my first terrain race and my intent was to complete it and have fun while doing so. I had a blast with my good friend. That being said, based on what I had seen on the website, this was not what I expected and needs alot of improvement.
-First, you shouldn't have to pay $10 parking. it would be one thing to pay $10 parking if there were other parking locations to chose from. However this was at Chicago Speedway in the middle of a masssssive field that accomodates enough cars for NASCAR race weekends. So you have to park at the field! So you're forced to pay. Why not just build this in to the cost. If I hadn't had cash I would've been screwed.
-2nd - There were not enough volunteers/spotters along the course. There were quite a few obstacles that had no volunteers/spotters there. NOT OK. And we completely missed one of the requirements (sand bag on our shoulders when you climbed up the stairs) because there were no sandbags when we went up the stairs. Half the time it was the people infront of you who were telling you what you had to do. People weren't monitoring the completion of the tasks either. At one location if someone had fallen it would've been up the the participants to go run to get emergency.
3rd- I had expected photographers along the way. They were only near and at the finish line. And I had to search through thousands of photos to find mine. And you actually do have to pay for them. It said photos were included with the price.
4th- we checked in no problem...they scanned the code on my phone. But as we're walking around, about 30 minutes later, we see a lady telling to everyone "if youre a participant in the race today, you have to sign a waiver!" (piece of paper). They weren't announcing that when I had checked in. And ummm....isn't this done online?
5th - They handed out the t-shirts at the END of the race when you came across the finish line. Hello, we're wet, and dirty with mud and dust. And they were WHITE t-shirts.
7th - there were no obstacles to climb under. Not ONE. I had been looking forward to that actually.
8th and then I'll shut up. - NOT FOOD OR DRINK AT THE FINISH. Any food and drink you wanted, you needed to pay for at the beer tent.
I don't know.....in general I'd have to say my overall feeling is that it was disorganized. No one on the bullhorn telling people when to line up, no signs pointing to where to go for things like hoses, the porta potties should have been at more than one location photo opportunities, food tent, gear check, etc.

Mini Monkey

I have run a few mud runs in the past and they were fantastic. My daughter wanted to race, so I found this one and she was beyond excited to do a run with obstacles and mud. There was not one mud obstacle. In total, I paid about $40 for my daughter to do obstacles she has at her favorite playground- which is free. I am bummed for my daughter since she ended the race and asked where the mud was, and I felt terrible since I had told her there should be mud, from seeing the advirtisements. Something needs to change here. I do not recommend paying for this race that is misleading from the site and advirtisements.

Great race

This race was great! The obstacles were fun and challenging. People said that their obstacles weren't stable, but every obstacle was in place and fully functional in our race and we were in a late wave- 1:15pm. Everyone was helpful. The race was fun and not incredibly competitive, people helped if you needed it on an obstacle. It was organized, well run and had great freebies from sponsors. We would definitely do another race with Terrain.

Loved it!

I raced the elite heat and loved it! The obstacles were fun and challenging and loved the mandatory obstacle completion for the elites. I don't really understand the negative reviews. Perhaps those people have never shelled out $200 for a Spartan. Terrain offers a budget-friendly OCR option that is professionally run and well organized. Many of the races are absurdly expensive so I will gladly continue supporting and attending Terrain Races, where the prize money rivals the other races and the entry is a fraction of the cost.

Elite Racers... Don't even bother. Not my first OCR and upon arriving, the disorganization was obvious. You have to wait in yet another line and physically sign waivers even though they sent emails prior to the race to electronically sign -- What was the point, then? There was music but no DJ, extremely limited sponsors and food vendors, not really a hyped up 'party' atmosphere so there was little desire to hang out before/after your race, the changing tents were tiny and NOT secure whatsoever (entrance flaps completely open with no way to securely close them) and were located at the entrance of the event so everyone can see both men, women, and children changing! That is unacceptable. The race itself was not very good. You start in a pool of water (which reeked of urine by the way) and the obstacles weren't too challenging, with some being repeated multiple times along the course. Good luck having your picture taken, too. I counted TWO photographers the entire course. The volunteers were sparse and there were many unmanned obstacles. No verification for bag retrieval, t-shirts, and race type. Basic and cheap white race t-shirt.

All in all, save your money and go for a more reputable and organized OCR.

Look Out Below...

This was my first OCR run, so I'm not basing it off expectations of previous races. Overall, I had a good time. Starting in a pool of water seemed very strange as it's not an obstacle and in Arizona, you dry off extremely fast before you actually get to the first real one. The name says it all, we ran through desert brush and dry washes full of sand, so you really do need to "conquer your terrain." My biggest issues that give it a 3 star review is repeat obstacles, 2 7ft walls to ascend and one 4ft one to jump over. Just pick a size, and do it once, and give us 2 different obstacles in place of the repeaters. Also, doing the inclined monkey bars over a pool of water, was unknowingly treacherous. My fiance slipped and fell in, and landed on the ladder used to get out of the pool! It wasn't bolted down to the side and no volunteers were there to see and fix the problem. Everything else was fine, but safety incompetence isn't good. Will likely do it again next year, and will definitely check the pool next time to make sure we can't get hurt by a loose ladder.

I only saw 2 photographers on the course, at the finishline and at the end for monkey bars, very disappointing. Few volunteers, many obstacles unmanned. Hoses were not hooked up (we ran the 1 pm) at the end to rinse off. No sanitizer in the porta potties.

First and last time. Poorly organized. One of those races where the organizers are looking to minimize their overhead and maximize profits. Obstacles were few and far between. They definately don't look to improve or add to their races.I paid extra for the 10K and no one checked to verify the others. Same medal for the 10K & 5K, cheap white tshirts with a generic logo that can be used in future races, same with the medals. I've run several other races and this was my worse experience.

Wish I could leave zero stars. The cargo net obstacle started falling down in Miami and they had to remove people from it and disallow the obstacle. Not one person ever checked bands to see if the competitive athletes actually finished the obstacles. AND my husband paid for the competitive wave and Terrain has YET to post the times for the competitive wave in Miami. We had signed up for Atlanta and I have tried to contact them multiple times with no answer so I have disputed the charges with our bank. Terrain is dangerous, disorganized, irresponsible and to top it off they have zero customer service. Never again. That fact that they are a qualifying race for OCRWC is truly sad.
