It's also a good thing that Strava introduced the means to hide your start and end of your activities rather than pinpoint one's home location for example. If one has a regular routine one may consider not even making your routes public.

A former Russian captain of the submarine launched missles into Ukraine was killed (shot to death) during a morning run less than a couple months ago near the Russian navy base. Assassinated by either Russian dissidents or Ukrainian agents. He posted his runs on the fitness app Strava and his Strava feed was being followed by the head of Ukrainian intelligence!

I typed his name Stanislav Rzhitsky into Google Translate and the copied the cyrillic text into the strava search. ( Станислав Ржицкий )

He was also a mountain bike rider and in the comments for a bike ride on July 9th people commented on it:

Jonathan Bird "Are you dead?"

and Gerrit Knol-

"ey mate. Hope you're doing marvelously well! Why didn't you upload your last run? Oh wait... 0:)"
