I'm also very into rock climbing, and of the approximately 15 guys I meet up with regularly, only one is my age. That's OK, though. In rockclimbing, I can keep up or even climb harder than a lot of the younger guys. And then there are the others so out there I'm not even close, like my 27 year old kid.
It's all fun. I just want to do my best to stay in shape and be out there doing it at whatever level works.
