AC and SC climbers differ in their risk profiles. Poorer route protection in AC resulted in more severe injuries. Yet in SC routes, good protection alone was not enough to avoid severe injuries. For prevention, climbers should be aware of the specific risks in AC and SC routes and should adjust their behaviour accordingly. Athletic skills were overestimated in SC, while alpine demands were underestimated in AC. A higher focus on visual and haptic grip control may help to prevent loss of hold. A careful lining of the rope into solid rock can reduce rockfalls for the seconder. Continuous attention is mandatory in rope handling and belaying. Applying more mobile pros is recommended in AC because they may shorten fall heights.
