This guy was following a woman I know. He was using strava and turned up with his camera on two occasions to where she was training.
His strava account is a dead giveaway, he only appears to follow women.
Strava is great but everyone should turn on their privacy radius around their house and place of work, if they run from there.
Turn on the request to follow, this means nobody can follow you without you giving permission.
And get rid of any randomers from your account, especially if the guy named in the article is following you.
