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!

good race, great price, one of the best finisher medals in OCR, monkey balls obstacle good finishing obstacle, really tested grip strength. Hope you come back to the burgh

Cheap and gimmicky: Avoid

Jul 26, 2016 by GR

1. The 10K race was not a full 10K and was poorly marked, leaving runners confused constantly.
2. The obstacles were cheap and easy, then the final obstacle (Monkey Balls) was near impossible.
3. If you do not complete Monkey Balls, you are DQ'd from the competitive wave, thus wasting the extra money you paid to run for prizes or placement. That is unfair for an obstacle so poorly designed.
4. Results were not posted at the race and, now, over 2 weeks later, still have not been posted.
5. Customer service is literally unresponsive, by email or by phone, and sent out a fake link to results that contained no information.

This is a cheap, gimmicky race that is poorly managed and poorly run. I would ask for a refund but no one can even get the management to respond!

Great Course For The Price

Jul 11, 2016 by Wes

Lets be honest, when you can run an obstacle race for under $50 you just sign up, right? So I did, and how grateful I am that I did. Having run a slew obstacle course and mud run races in the past 5 years, I have seen the best of the best and worst of the worst. Terrain Race is in my top 10. Some reviews I'v read complain that the obstacles are too basic or that there aren't too many, but in my opinion, the obstacles were perfect. There were plenty of walls; 6-footers, 8-footers, and the 12-footers with a knotted rope and foot holds. There were also monkey bars and cargo nets. I agree with some statements that you get what you pay for, and for $35 what can you expect. Well, let me tell you that you can expect the event holders to live up to their name. This race made the best use of the terrain available and luckily for me, western Pennsylvania is full of hills, mud, rocky streams and even old mine shafts. That's not to say, however, that the terrain is the main obstacle. I was delighted to find tire flips, tire pulls, and a rope climb all conveniently located at the top of the largest hill on site. As for the infrastructure of the event, registration and packet pickup were a breeze. There were no lines and everything was very organized. The free bag check was very safe and secure and the changing tents, though a bit small, were private and sufficed. There were plenty of hoses provided to clean up with and the water pressure was enough to do the job. All in all, this was a great event, focused on both fun and being physically challenging. I hope to see more of these races in more locations, as well as back here in western PA next year.

Event Name: Atlanta Terrain Race 10k 2016 

My daughter and I have done myriad OCRs and this one fell short in many areas. The course itself lived up to it's name as it did have multiple terrain changes and quite honestly if they would have just taken a little more time to fix a couple of things it would have been real good. First of all OCR 101 - We do NOT want hot water at the hydration stations on a "10k" OCR! - I say 10k in quotes cause it was actually by multiple GPS devices 7.2 miles instead of 6.2. The other big problem was at the end, we wanted to buy a water (We were in the last wave) and they would not let us even though they had some in plain sight. The guy said his boss said he could not sell any more and the only thing available were the beers for the race tickets. That is all fine until you realize we just went through a 7+ mile OCR with nothing but hot water to hydrate! With all that, A bad day on the OCR circuit is still better than a good day on the couch! And on another positive note: I really do like the Terrain Race medal!

I do alot of obstacles races and this was by far one of the best, not to mention it was very affordable. Bad assistance medal to!

Terrain Race Portland

May 24, 2016 by Tracey DuChene

This by far the most challenging course we have raced yet! Perfect blend of terrain, obstacles and wave times. Although it seems groups form on the race course, we found that the course allowed people to break quickly. Love this race, cant wait to do it again next year!

good course, terrible lines

May 01, 2016 by C

Having done this event last year and enjoyed it, I was greatly disappointed by the logistical failing of this years race. The lines were insane both on and off the course. The line for the last obstacle was so long that I just gave up and went home.

Fun in the Sun

Apr 07, 2016 by Jack Kenney

I signed up for the Terrain Mud Run in Temecula (SoCal), California with zero expectation. None. Nada. Zilch. This mud run thing was something I had never done. What could I expect?

The idea of competing in a "mud run" came to me after seeing a Spartan event on television while slowly working out late on Tuesday evening. Over the course of a year I had lost nearly 100 pounds and working at the gym had become a little easier, but I no longer had a goal.

I need a goal.

After watching the Spartan event I immediately went home and on-line, watched videos, did research, and discovered the Terrain Mud Run SoCal to be the next, closest event.

So I signed up.

Upon arrival at the venue (the dry dirt and wash behind Storm Stadium) I felt apprehension. Being a little older...okay a lot older than the average runner I felt out of place. But only briefly.

As I warmed up I got excited. It was a clear, warm day and lots of happy people milling about. People of every shape and size ready and willing to go.

At 1130 I wandered to the starting line and discovered the pool we would start in. Not happy. But whatever. In a blink we were off and running. And panting. I had not trained well-enough for the running. Note to self.

First obstacles were walls and I made it over relatively easy. Except the 12 foot. A little trouble there.but made it. Then more running. And running. And a wide variety of obstacles I had never experienced. Short rope climb (fail), very low monkey bars (fail), mud pit, tire climb, wreck bag carry, balance thingy, cargo net, and so on. And, at the end, the thing over the water with the hand grips and balls and whatnot. Immediate fail. Apparently my elbow injury is not entirely mended.

In the end I had fun. The goal right?

How was the course? I dunno. Good? My first time. So good for me. Not enough hills. I do actually run in the hills by my house and enjoy that a great deal. The festival area was meh, the tee-shirt okay and the medal bitchin! (Totally)

Would I recommend? Yeah, absolutely. It wasn't easy, it wasn't amazingly hard...it was the bed on the end...just right.

Will I go again? Yes. I have a time to beat and an age division (old man) to come in first.
