The Inferno is an extreme obstacle course biathlon featuring a distance swim and is now offered in two lengths (13.1 miles or 6 miles). We’ve developed a number of challenging obstacles spread out over a rugged terrain in the scenic backdrop of the Pacific Northwest. You’ll climb hills, haul sandbags, flip tires, climb ropes and walls, traverse monkey bars, and now SWIM your way to the finish line! But what makes us really different than all the other races out there? You won’t find any mud obstacles on our course! Why? Because mud is not an obstacle, it’s a photo op!
