What term describes the ratio of fall distance to rope length in challenge courses?

• A. Fall factor
• B. Fall distance
• C. Rope length
• D. Safety factor

Answer: (A)

Fall factor is the ratio of how far you fall to the length of rope available to arrest that fall. It’s found by dividing the fall distance by the rope length between you and the anchor. This matters because a higher factor means a larger dynamic load on the rope and anchors when the fall is arrested. In practice, longer rope relative to the fall distance reduces the factor, lowering the peak forces and improving safety. For example, falling 3 meters with 15 meters of rope yields a factor of 0.2, while the same fall with only 6 meters of rope yields a factor of 0.5. The other terms describe separate ideas: fall distance alone measures how far you fell, rope length is just how much rope is used, and safety factor relates to overall design margins rather than the fall-to-rope ratio.
