Do technical mountain climbers practice an actual "fall" (in training or otherwise) to experience what it is like being stopped by their rope(s)?

 Yes, technical mountain climbers often practice simulated falls during their training. This is typically done in a controlled environment, such as an indoor climbing gym or on outdoor practice cliffs, where safety measures are in place.

Simulated falls allow climbers to experience what it's like to be stopped by their rope systems, such as belaying techniques or other safety mechanisms like anchors and protection devices. By practicing falls, climbers can build confidence in their equipment and techniques, as well as learn how to properly react in the event of an actual fall while climbing.

These practices also help climbers and their partners refine their communication and coordination, ensuring that they can effectively manage risks while climbing in challenging terrain. Overall, practicing falls is an important aspect of technical mountain climbing training to enhance safety and preparedness for real-world climbing scenarios
