I retired last year (65), before that I had been fulltime bike commuter for 20 years. I was always a rain or shine, no matter what commuter. My commutes were:

33 miles R/T, ~1500 feet of climbing
40 miles R/T, ~1800 feet of climbing
18 miles R/T, ~1200 feet of climbing
39 miles R/T, ~2000 feet of climbing

Main bike was a Titanium cross bike that I continually upgraded. I put well over 70,000 miles on that frame. I don't miss anything about working, but I really miss bike commutting.
