Dirty Dozen Obstacle Trail Race

Climb, jump and run through the 12 obstacles that make up the 3rd annual Dirty Dozen, a 5K and 12K obstacle trail race. These races, which take place on Saturday, October 11 the morning of the USNWC’s Fall Finale, will test your strength, coordination, and stamina as you race to the finish. Though not officially a “mud run,” we recommend wearing an old t-shirt. We call it “dirty” for a reason.
