Although I’m certain I’m not as physically fit as you seem to be I think we’ve enjoyed some similar hobbies. When I was young I was involved in karate and Kung fu, I’ve been shooting my whole life and love bicycling (road type).
Have you considered photography? It’s another type of shooting. I discovered and explored things and places I never never would have otherwise. It can be physically demanding or not at all. Unfortunately, like most hobbies it can become a money pit.
