Dirty Dozen Obstacle Trail Race

12 obstacles and 12 kilometers stand between you and the finish line in the 5th annual Dirty Dozen obstacle trail race. Looking for a shorter race? We’ve got you covered with the 5k obstacle race as well. While this is not an official “mud run”, expect to get dirty along the way (we recommend wearing an old t-shirt for this race). Put your strength, endurance, and coordination to the test as you navigate your way through several physical challenges along the USNWC trail system, then celebrate your accomplishment with a fun-filled day at Fall Finale.

    Where can we see a list of obstacles, are there only 5 for the 5K, and is there any video of the previous 4 years’ events? (I searched YouTube, couldn’t find any yet).

      Hey Jeff, our obstacles include cargo net climbs, monkey bars, rings, and culvert navigation among many others. There are 12 obstacles on the 12k and 6 for the 5k. Please stay tuned to the Dirty Doze race page for more information closer to race day.
