In the middle of the year, I moved from a very hilly area to a flat area. In the hilly area I was usually around 7k-8k miles per year with around 450k feet of climbing. I expect that my first full year here on the flatlands (2023) will probably be under 100k climbing.
Fun story: back in the hilly part of the country, I once went out on a big climbing event (group ride, but a big one) that is always held right before Christmas- so, right near the year's end. After the ride, we were in the parking lot, looking at our computers, and a guy said, "Hey, I hit 10,000 miles today...And a million feet of climbing." That impressed the hell out of me.
