Course Details

How hard is this?

Our obstacles are designed so you can conquer them on your own but it’s always nice to have a teammate help push you over these huge walls. Even the competitive athletes will struggle and instead of a penalty when you can’t conquer an obstacle, you just keep trying until you do! For open waves it’s fine to skip an obstacle, but the competitive will be disqualified if they do.

Extra laps

Want to race more than once? For an extra $15 you can run as many laps as you want. This is great if you want to race the Competitive wave and then again with family or friends new to obstacle races. You’ll get a special wrist sweatband and each lap you complete you’ll collect a monkey pin so you can brag after the race.

Where’s the map?

Part of the difficulty is we won’t post a map until race day! With surprises around the corner the race becomes more challenging but we will have a huge map for you to study right before the start cannon goes off.

What is included in the registration fee?

Shirt – Comfy and stylish, plus free Gear Check to store it at.Medal – This is some serious bling!Bib – Hang your wall to brag about your achievements on the course!Photos – Photos of you on the course.Obstacles – 25+ obstacles to conquer!


Available Start Times

Early waves fill up fast, register now before the spots are gone! If you’re trying to join a friend in a wave that is already full, ask them to create a team and when you join their team you can race at the same time they are.

The Competitive waves have prize money and cost $15 extra.

Early waves are super popular and cost more, but don’t worry, the later waves are just as good!

The fastest female and male athletes in the Competitive 10k will be awarded gigantic monkey medals and the 10k distance will be awarded cash prizes: 1st place – $200, 2nd place – $100, 3rd – $50.


You can race on a team or solo, but mud runs with friends are so much more fun!

When signing up you will have the option to create a new team or join one. If the time the team captain chose is full already, click FAQ in the menu above to see details on how to join their same start time.

Packet Pickup

The only packet pickup is on Saturday morning before the event. Gates open at 7:00am.

You can pick up your friend’s packet but you must have a printed copy of their Check-In Ticket.

Please arrive 1 hour before your wave start time to allow time to get your packet race morning.


All athletes in the Competitive Wave and Premium Waves (8:15, 8:30, 8:45) will be timed. Your time will be slower than a 5k or 10k race, but it’s always nice to see how you rank compared to fellow athletes.

We use chip timing so you can see how fast you really are and we provide you with a free printable finisher certificate online after.


We create a finish area that includes many exciting obstacles for spectators to watch their family and friends on. There is no fee for spectators.

Kid Races

Terrain is about families and friends and working together to conquer this course.

Kids 7-13 years old must have a parent race with them on the 5k course and the parent will need to buy a regular 5k entry.

Mini Monkey Course

Even younger kids can compete on a half-mile course for ages 2-10 years old. One adult can run along the course to cheer their youngster on. You’ll see several wave times available for the Mini Monkey race at each race we host.
