As the name of the obstacle implies, you’ll be running among pits of blazing firewood. You can expect flames at least 4 feet tall. While running between the flames might seem like the most intimidating aspect of this obstacle, Mudders℠ will soon find that they must leap over the final pit of fire. This leap will land them in a pit of ice cold water, quickly sapping any of the warmth they may have gained from flames. This is no campfire and marshmallow adventure in the woods, so don’t even bother trying to train for Fire Walker.
