Only 69 here. I ride about 500miles/mo, at varying intensity about 8 or 9 months/yr, some winter skiing (former ski patroller) and 2 kayaks help as fill-ins. If I was at the gym regularly (only sporadically), there would be no time for walking 80mi/mo. After retirement I was a Forest Service Wilderness Ranger (2 summers paid, 5 summers volunteer) and 80mi/mo with a 35# pack was typical. So I like hiking, and still hike once or twice a week on the local hilly trails, but probably only 20mi/mo.
If I were you, I would reduce either bike or hike mileage and find a less physical hobby for enjoyment into your next decade.
What amazes me is that you can get a max HR up to 175! I can't get above 155. Resting HR (taken early morning) is low 40s.
My opinion: At my age I can only achieve a certain level of fitness without changing much of my life routine, possibly negatively impacting other family members. Going longer, faster, harder for me builds fatigue not fitness. At your level a 'senior fitness coach' might be the best idea. Yoga? Meditation? Wholistic counselor?
