GPS traces used to target bikes

Strava has an option to not show the start/end of rides within a user defined radius. Only problem is that with enough rides it's pretty obvious the location will be somewhere in the middle. No such thing on garmin connect as far as I know.

Garmin Connect has a private option.
You can make all or some of your rides private.
Click the padlock or change your settings.
If you change your settings to be private you will have to manually lock and rides already logged.
