Pretty much the same mileage: 5,800 miles, I was aiming for 6,000.
More hours, because I added walking and jogging later in 2020. I already have more hours walking and jogging by mid-January 2021 than I had in all of 2020. And only two road rides this year.
Lots more solo rides in 2020. Zero fast club rides after February 2020 when the Super Cooties Apocalypse seemed imminent in Texas. The fast clubs continued riding as usual, but at age 63 I can't afford to take chances. Those guys and gals are all at least 20 years younger.
Only three or four casual group rides in summer with reduced risk of swapping airborne spit and snot. And I wore a surgical mask on most of those, not a problem with zone 1/2 rides. Never wore a mask on solo rides since I might see one person in 20-40 miles where I ride.
And I did more walking and jogging by autumn, 3-5 miles a few times a week, so my overall hours increased, although foot-oriented exercise doesn't add much mileage.
