Climbing, the gear is all rated to lift 2 tonnes, so a medium sized car. It won't snap with you on it.
Edit: sorry this is misleading, climbing is not harmless, and a lot can go wrong even with good equipment. The point I wanted to convey was that equipment failure is an unlikely cause of problems for climbing
I’m a climber and while yes, the gear is very well made and over engineered climbing is still quite dangerous. That rope could be rated for 500KN but if you repel off the end of it you’re still going for a fall.
Or other forms of inexperience. If you were climbing a rock face and didn't realize the part you were trusting your life to wasn't as stable as you thought it would be and your attachments give out.
I had a huge carabiner holding a free climbing rope fail on me at my local climbing gym. Dumped me at least 15’ and I broke my foot. Definitely a weird one off but it’s not always the rope that fails.
