6. Cliff Hanger
Cliff Hanger is impossible to do without your teammates. You climb together up a 40-foot “cliff” of very wet mud and dirt. Handholds and footholds are in short supply, if there are any at all. If you try this alone, you’ll scramble upward 10 feet, and slide backward into a muddy pit below looking like a fool. Most Tough Mudders hit the slope together at a sprint, pushing and pulling each other up.
Hint: Take it easy. Link your hands together in a chain with your teammates. Edge up the slope slowly, step-by-step.
