You don't need strava to be a local legend. I bet you if I asked anybody in a mile radius of your house about the guy on the unicycle they would immediately know who I'm talking about.
Supposedly there is a guy who does laps up and down Rio Del Mar hill (steeper and longer than anything I've ever done).
I saw him once when I used to run - about 10 years ago.
There is another older dude with a ponytail that rides Beach Rd and along the beach path down to Seacliff.
That is actually a fun ride but I haven't been down there in years either - too crowded.
I saw a younger girl down there on the beach path once too. All of them ride 36 inch wheels.
Every once in a while someone in the neighborhood will drive or walk by and tell me they have been watching me for years.
