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.
