@cookeaa you would think so wouldn’t you … that’s the option I have activated, but the important text is ‘on your strava profile’. So as I understand it people cannot access your profile unless you allow them, but this is shortcutted by this, appearing a bit further down the page you link to:
“Keep in mind that your activities are still visible in public locations like segment and club leaderboards, even if the clubs are listed as private”
A bit mad really becuase unless you make all your activities private then you will inevitably appear on a segment leaderboard even if your xth out of x people! I think this is what is happening in my case.
