Thanks for pointing out these Strava heatmaps; never knew these existed.
Mine cover habitual terrain and routes here in SoCal. It's fun to switch between years and all-time.
Traversing so many parts of The City seems insane to me!
Hell, just driving around those parts can make you go berserk. haha
Like you, I set my 2022 target for 6,000 miles. A mild bout of covid proved a big setback for me.
At the mid-year mark, I totaled a little over 2,400 with about 100k feet of climbing.
With a cruise vacation looming, it looks doubtful for me to reach my goal. I hit 6k miles the past six years.
