    What's a Terrain mud run like?

    Terrain Mud Runs are races that YOU will conquer.

    Instead of branding our company with an angry connotation or a themed race such as a pirates, warriors, soldiers, etc., our athletes are proud to conquer Terrain Mud Runs as themselves. You'll be proud of your OWN accomplishments of navigating a challenging and fun mud run course. Terrain is about your own accomplishments. Terrain is about you.

    You won’t find gladiators forcing you to take the plunge into a “scary” swamp. We know that you don’t have to pretend to be something else for the day to reach your goals and be your own hero.

    Instead, you’ll take that leap as you, not as a themed character. You’ll find that you are more than a number on your forehead or an identically dressed spartan. You’re part of the Terrain family.

    Throughout the race you’ll be challenged by obstacles so large they take heavy machinery to construct. On the other side of them you'll relish in your glory of conquering them as yourself.

    We all have our own obstacles to tackle and completing your Terrain race will be an awesome way to overcome them. It’s a course we build and we call it Terrain. But in the end, it’s your race, it’s your terrain.
