    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.

  • Awards


    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.
