Hi Alan
I'm 76 and up until about a year ago was still climbing regularly. I'll echo what others have said, fear of injury was becoming greater than it used to be. Something like a broken leg would be hard to cope with, and even minor injuries and strains take longer to heal now. I found this particularly with rock climbing when after a couple of strains to my right knee joint due to pushing up on it at a slightly unnatural angle I was off climbing for several weeks each time whilst hobbling around, and I decided to concentrate more on walking, which I can still enjoy (well! under normal circumstances!!)
Another problem is failing eyesight and this has led to my tripping and falling over on rocky paths several times which is knocking my confidence. I used to be able to boulder hop and run down mountain paths, but unfortunately no longer, as I have to pick my way, particularly going down, with care.
I am much slower now than I was, even in my early 70s, but so long as I give myself enough time, I can still get up hills. Two months ago I walked up Table Mountain in South Africa via a route from the Pipe Track. The guide book recommended time was about 3 hours, it took me 5 hours in 32 degrees heat, but by going steadily I still did it, and enjoyed it.
So whilst sadly I have decided to stop rock climbing, I am still enjoying walking, when I can I do about 8 to 12 miles a day, and long may that last!
