Low 50's here. Long term riding, but mileage has increased significantly in last 3 years, with 2018 over 1000 miles more than 2017.
For the most part I run Strava in the background for ride logging, although I am aware of a few segments.
Only been recording on Strava heavily for about 3 1/2 years now.
Last year (2018) I logged 201 PRs, mostly "JRA PRs". Some on regular routes, many on infrequent routes, so perhaps they don't count as much. But, I am still periodically picking up local PRs.
Overall, not feeling like pounding hard on a lot of my heavy hitting segments that I know about, but I did hit a couple of them.
I think I lost a KOM, and picked up a different KOM last year
Not one of the fastest local KOM's.... but nonetheless...
I also logged my fastest descent speed ever last year at 54.1...
