Are you saying that you don't want to see your activities in the Activity Feed on the Connections page? I don't believe that this is something you can change. This displays your activities, and those of all of your connections.
I am finding this same problem as well. When I upload an Activity it seems to now duplicate itself in the Your Connections Scroll down window on the right of the page. This has only happened in the last week never before in the 2 years previous.
Anyone know why this is happening or how to remove them from Your Connections?
Having the same problem. My connections used to only show my friends activities; not mine. Then about a week ago, all my activities are also listed there. Very annoying. Why would anyone want to see their own activities in this list? Common Garmin!!
