Wow, what a fantastic event in the pines of Flagstaff! This was a challenging and well designed course that was perfect for all abilities. The weather was perfect!
There were a lot of great things about the event overall I'll comment on like the layout, vibe and the course. The vendor tents were stocked full of great gear to purchase and they gave away so many items that helped out a lot. They had a pizza truck show up with deliciously over sized slices for only $4! The beer was super cold and delicious and all of the volunteers were phenomenal. The porto potties were easily accessible and very clean as well. Let's not forget parking was free! The medals are the BEST I've ever seen and we always get super comfortable shirts to wear. If you do extra laps, you get a secret pin as well. Because I did 2 races this year, I got a second medal and I'll get another unique medal when I complete my third race in October. Overall, this was so worth all the money paid and way better than Spartan.
The course overall was perfectly designed. The obstacles started slow and a nice run through the woods got the body all warmed up. The hills were a nice grade to get the heart rate going and the descents were a nice way to cool down after the climbs. The thing I enjoy about Terrain events is that they run you through mud but balance it out with a lot of full on water obstacles to was you off. There were plenty of walls to climb, wreck bags to run with, tubes to crawl through and mud pits to navigate. The water was just chilly enough to shock you but also a perfect way to cool you off as the temperature of the day climbed. The runs were nice and long in a few section for some great forest running and the natural obstacles like logs, water holes and walls added to the challenge. They had 2 fully stocked water stations to serve the 10K course (1 for the 5K you could visit twice) and plenty of free water. The volunteers were also super nice and friendly which helps when you're out there hurting. In the end, the course was tough enough to tire you out but fun enough to make it an extremely rewarding experience.
There were a few things though that they could improve on:
Some consistent music would be great to keep the event moving and grooving. They should make the very first stop into the event a table/shade structure that has the waivers in it for people to sign before they ever get to the registration tent to help speed things up. Also, there was a mud obstacle that had extremely sharp rocks that people were getting hurt on. Maybe the grounds could have been tested before unleashing the racers. The slides are brutal to go down because they aren't slick enough and the rocks underneath them tear up your backside up. Finally, there were no showers to rinse off before heading home which aren't a really big deal since we get dunked before finishing but it would be nice to have that option.
In summary, this is a top notch event and way better that Spartan. Everyone involved is approachable, friendly and positive. I not only recommend this series to people, I also try to promote their events as well since they have shown me they are genuine and sincere people.
I'll see all of you in Tucson!
Something for everyone!
Excellent run! My son and I will probably do many more.
The accessibility of the course was wonderfully balanced. There was something for everyone: long stretches of trail for runners, opportunities for team-work, individually-challenging obstacles, and everything in between.
Terrain Mud Run
Why are you now charging a mandatory insurance fee - I am paying as much for insurance as I do for 1 admission to run. The government already mandates that we have insurance - I certainly don't need to be told I need insurance to run an obstacle race. We have enjoyed many of your races and you are turning this into a money pit, charging fees for parking and insurance. You are getting no better than all the other mud runs in town and the obstacles are not as good. This will be our last season racing if this continues.
The BEST race ever!
This was my first Terrain Mud Run and it was the first 10K I've ever entered as well. I've done Spartan, Warrior Dash and a few other races but this course was superior to them all. The water obstacles were everywhere and it was the perfect combination of getting muddy then rinsing off to get even more muddy. The walls were places perfectly except the one on the 10K course after the super deep water hole because people were slipping off the top and falling. The tire flip was great and I loved that you drench us before the finish line.
Thank you to the entire staff for being super nice and putting together a course that was very challenging but fun. I look forward to future courses and the in town courses.
Terrain Mud Run, the start of a new addiciton!
This was my first Mud Run and it was AMAZING! My daughter and I were a little nervous to try it but had an amazing time! We are now addicted and can't wait for the next one! I have nothing else to compare it to but if the rest are anything like this I am going to every one that I can get to! It was challenging but the rest of the people there were very nice and very supportive. The team work from people you have never met before and may never see again was great to see. Thank you for the great time and great memories with my daughter. My only complaint is that there could have been another water station on the 5K course but other than that amazing time.
Terrain Mud Run the next Tough Mudder?
I did the 10k elite race in Flagstaff and it was awesome- Ive never been so tired. It is a smaller operation than some of the bigger series like Spartan and Tough Mudder but you would never know it because they do such a great job. The obstacles are none stop, and the terrain is tough, uphill, downhill, over, under, and plenty of mud. The stations had water AND gatorade and were well spaced. There is very little waiting, if any, at the obstacles like at some other races even if you don't choose the elite heat. Everyone is so friendly and helpful, you can tell they care alot about their operation. You get a nice shirt, medal and bars and fruit at the end. Cant wait for the next one!
Impressed. A Real OCR..Not just a mun run!
I wanted to give this a review from a person who has only done Spartan OCR races. At first I was thinking this might be another "mud run" cheesy obstacles not very challenging. After speaking to a few other top athletes they said Terrain has really stepped it up. And I can honestly say that did that. Plus they also added an Elite start time. This was a great course. A nice runners course with some very challenging obstacles. The spacing on each were just about right. Only a few course direction problems but they all have that. I found this Phoenix location at Rawhide to be a great location for this event. I would only say it might be nice to have a few other photographers around the course. This one only had one. And I do like the medals and Terrain's are large which I like, plus they are orange!
Funner than a barrel of monkeys
I had heard that the Terrain Mud Race events were good, so on May 3rd, 2014 in Phoenix I decided to find out for myself. Let's start with what I liked about the event. The volunteers. They were helpful and plentiful. From checking in to making sure racers were directed to the correct course for their distance, the volunteers made it a smooth process all the way around. The course. I would be hard pressed to find a course that would measure up to this one. The obstacles were a great mix of physically challenging and just plain fun. The distance between obstacles was excellent. Not once did I feel like it had been awhile since the last obstacle. They kept them coming. The medals. These bad boys were the best finisher medals I have ever earned. They were solid, big, in the shape of the Terrain monkey, and a beer opener. A perfect 10/10 and I would score it higher if I could. Now for the something I would like to see improved. The bag check. Checking in a bag consisted of being given a red piece of tape to write your name on and then attach it to your bag. To retrieve your bag all that needed to be done was point out a bag and say the name clearly written on it. This bothered me because my bag was the designated holder of wallets, cell phones, and other valuables for the entire team. To pick up my bag did not require any kind of ID or matching of bib number to a tag on the bag. Anyone could have said the name on the tape (which was in plain sight) and taken our valuables. This is a simple fix and I hope to see an improved bag check process at their next event in Flagstaff. Overall, this event lived up to the hype. I was impressed with it and will surely reccomend Terrain eventsin the future.
Probably the best race you don't know about (yet)
Most "small" events that only operate in one or two states and host 3 or 4 events in a given year are usually somewhat below par - that is clearly not the case with Terrain Mud Run. From the quality and number of obstacles on a 5k to 12 mile course to the friendliness and professionalism of the staff, you'd be surprised that you weren't at one of the "big" name OCR's with ample resources. I interviewed the owner, Jerry Foreman, and we got into a long discussion about obstacle spacing, specific groupings and what it takes to build a fun, challenging, and well-paced course - this guy clearly gets it and it shows in the enjoyment of everyone who challenged all of the different distances of the Terrain Phoenix course. I chose the 12+ miler, and while it was 2 somewhat tough laps around the course which offered a dozen or so obstacles, it surely wasn't boring. Actually, Terrain Mud Run jumped up my list of mud Runs & OCR's to the top 3!
With no "theme" like zombies or warriors to make Terrain extremely memorable, they may not have the buzz of many large races have - but while I was speaking with other racers, I came across several repeat offenders who look forward to the Terrain events in Tucson, Phoenix, Flagstaff and Las Vegas... I know in 2014 I will!
