Rock climbing is a high-risk sport. Not using safety ropes (that is, “unprotected climbing” or “free solo climbing”) will greatly increase the risk of falling and may lead to serious injury or even death. **We do not encourage anyone to perform unprotected climbing**, because any mistakes can be fatal. If you still decide to try, please be sure to carefully evaluate your abilities and take the following measures** To minimize the risk** (but not completely eliminate the risk)： ### 1. **Strictly evaluate one's own abilities** -Make sure you have ** fully mastered** every action of the line. It is best to practice repeatedly with rope protection to ensure a 100% success rate. -Your technical and psychological qualities must be extremely stable, and you can calmly deal with emergencies (such as slippery, broken hand points, etc.). ### 2. **Choose the right route** -Choose a route whose difficulty is much lower than your limit to ensure that every action is easy and controllable for you. - Choose ** short route** to reduce fatigue and loss of concentration caused by long climbing. - Ensure that the rock wall structure of the route is stable and avoid loose rocks or unreliable grip points. -The ground environment is ** relatively safe** (if there is a buffer platform below or protected by partners). ### 3. **Adequate preparation** -**Warm-up**: Fully exercise your body to reduce the risk of muscle strain or cramps. -**Check equipment**: Even if there is no rope, make sure that the equipment such as shoes and magnesium powder is in good condition. -**Familiar with the environment**: Understand every detail of the route, including possible rest points, escape routes, etc. ### 4. **Mental preparation** -It must be carried out in a state of complete calmness and concentration. Any fear or distraction may lead to mistakes. -Anticipate possible unexpected situations (such as hand slippage, foot slippage) in advance and formulate coping strategies. ### 5. **Emergency plan** -Although it is a solo climb, it is still recommended to have a reliable partner present in order to provide assistance in an emergency. - Ensure that **Medical rescue** can arrive quickly (such as close to the hospital or carrying emergency communication equipment). ### Emphasize again： Free solo climbing has always been extremely controversial in the global rock climbing community, and many senior rock climbers strongly oppose it because of its high risk. Even the world's top freehand rock climbers (such as Alex Honnold) only dare to try on a very small number of routes after several years of preparation. **There is only one life, please cherish it**. If you are interested in challenging yourself, you can consider other ways, such as： -**Red Line climbing (Redpoint)**: Practice repeatedly under protection until the route is perfectly completed. -**Bouldering**: Low-altitude climbing, with crash pad (buffer pad) protection. The pursuit of limits is admirable, but the essence of the spirit of climbing is to find a balance between adventure and safety. I hope you can enjoy rock climbing and always put safety first.
