Distance per ride seems like an odd metric to me. Too many confounding factors involved.
FWIW, I ride about 25 miles or so a day during the week, and a longer ride on weekends. That’s down from my pre-retirement daily commuting distance of 34 miles a day, but it includes about 2500 feet of daily climbing, and my commute had virtually no climbing.
My endurance is definitely waning and I’m not as tolerant of heat as I used to be either. Getting soft, I guess.

I agree, a 25 mile ride with 3,000 feet of climbing is more difficult for me than a 50-mile flat/light roller ride. Lot's of caveats.
