that's great, but it's not proper training, it's a hike, fantastic activity but (especially growing older) our life is mostly sedentary and it helps a lot to do a proper sport or intense activity at least 3 times a week (i personally workout every day, but sat and sun, for 1 hour with a high intensity sport, not weightlifting). The older you grow the harder it is for the system to process the amount of stuff we eat (especially high calories, highly processed food that is available nowadays) and doing a high intensity activity (heartrate up, muscular stress etcetc) is, in my opinion, fundamental and often ignored by people.
