Big Dog Brag transforms the natural obstacles of Colorado’s rugged terrain into 25+ muddy obstacles on our family-friendly 5k and 2k courses. Splash down the 70-foot MUD SLIDE, climb over cargo net canyons, slog your way through real mud pits...not just dirty water, rope climb on Colorado boulders, balance on swinging bridges, experience the Tarzan swing and sprint across the floating platforms. You can race with your best buddies to the finish line or soak up each challenge at your own pace. Get dirty with Colorado's most affordable five star rated mud obstacle run!
