If your true interest is in the mountains, then I would cut out the sports that conflict with that priority. Or accept a lower performance standard in your main pursuit.
I used to bite off more than I can chew, and I was constantly stressed by it. The easiest way to balance my interests was to eliminate lower priority items until I only had one left.
That’s probably not what you wanted to hear, but in the long run, it’ll be the most effective.
