This obstacle normally heads up the beginning of the cold-water obstacle section, ensuring you are soaked and freezing to the bone. Metal cables draped in a plastic sheet span the 70-foot distance, 10 feet above a freezing lake. Cross the cables, but beware: if you fall into the lake you receive a penalty and have to stand shivering onshore for five minutes before continuing.
Hint: Swing your body on top of the cable and straddle the cable with one foot resting on the top. Lay your body face down and shimmy along the cable to the other end.
