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.


DIsappointing

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.


FIND ANOTHER RACE!!

May 06, 2017 by Kressa Peterson

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.

Garbage! So many fees and customer support is THE WORST!!!!


Mar 27, 2017 by Chad Mills

I signed up for this race months in advance and honestly I didn't have high expectations after reading some of the previous reviews about it but I wanted to find out for myself (kinda like movie reviews, never believe them unless you see it) So figured why not it was inexpensive and lets see what they are all about. So I entered the elite wave or competitive however you want to title it as I do every OCR. To my pleasingly surprise this was nothing like a movie critics review who said oh this is not great blah blah blah. So what I'm saying is this race was one of the best kept secrets for those who have not run it. I have run Spartans, Conquer the Gauntlets, Green Beret Challenge, and the list goes on and this race was on par if not better then some of the others. I would compare it to if you took Conquer the Gauntlet and The Warrior Dash and collided them. It had a good amount of strength to endurance ratio mixed in. There were monitors at every obstacle to make sure people did not cheat and actually completed them. Water stations were manned and had plenty of water available. The trails were marked perfectly so there was no confusion where to run. The whole venue was set up great. It was one of the most organized races I have done. If your one of those folks who likes boring starts, boring obstacles, no mud, or staying wet the entire race then join your typical movie critic and live your average life on the other hand if you want an exciting challenging competitive race that does not break your piggy bank to sign up all the way to the day of the race. Jump on the best kept secret in the OCR world!!!!!

I ran the 5k elite heat in Houston. This was my first Terrain Race and first elite heat. I've done other OCRs open heat before.

1) I don't understand the idea of starting in a water tub (especially when it was 48*, but it did make for a good psychological obstacle.

2) On the monkey/hanging ball rig, the rules state you can use 2 lanes. The volunteer watching it yelled at me to only use one lane. Volunteers need to know the rules.

3) According to the website, the 5k competitors were supposed to get prize money, awards, podium time, etc.. They only did it for the 10k racers. I wasn't in contention for the podium but now I'm glad I wasn't because I would've been pissed.

4) No free beer? WTH?

5) The 2017 shirt design could use some work. My kids liked it and it looks like a kid shirt.

6) I will say the kids race was great and my kids liked it a lot.

Summary:
A good race that's trying to spread out. If they do some tweaking it'll be a lot better. I'd consider doing it again, but they need to take some of the reviews and make some improvements.


1st time racer

Aug 27, 2016 by 1st time racer

This was my first race. I did it to get my daughter out running this summer. We had a lot of fun. I've run 2 1/2 marathons, and a bunch of 5K's. This one seemed very unorganized, but it is my first mud / obstacle race. While we were waiting to start the final obstacle collapsed. Fortunately it looked like nobody was hurt. Because of that I was worried on all of the high obstacles with my daughter. The obstacles needed employees stationed at them, limiting the number of people on them at a time.
***If you take away the collapse and my worry, it was a four star event because of the cost. I am knocking it down to 3 because of the unprofessional, and frankly dangerous conditions. However, if you are safe, ok with just rolling with the puches, and looking for a fun run, this is it. By far the cheapest race I could find, which is why I was able to just go with the flow.


Not for Elite Racers

Aug 24, 2016 by JH

To be fair I signed up for both the competitive 10K and the open 5K so that I could run later in the day with my daughter and my girlfriend. The 5K was fine. The issue I have is with the competitive 10K....that I paid EXTRA to do!

1. No course map so it was very confusing for both myself and spectators plus the course was not well marked.
2. Unlike some other races the people manning the obstacles did not appear to work for terrain. They seemed for the most part to be disinterested and uninformed. One of them saw my GPS watch and asked ME what mile we were at in the middle of the race.
3. Most upsetting has been the inability to get the results for the race. If I pay extra to be in the competitive heat I would expect timely results. It's several days after the race and still no results. I've reached out to customer service via email, phone, and text and have received zero reply.

Side Note: while it didn't happen to me the final obstacle of the race collapsed sometime in between the competitive heat and when we ran our open heat.

Elite racers...don't bother!
