I see the Garmin connect site is doing a complete makeover. MAybe by some miracle they look at the facebook sharing.
Hi guys, I found the way! It seems that GC added this feature on the 'Modern' view:
- switch to 'Modern view' (top right on GC page)
- on the activity clock "Go to Full Page" (you'll find the option on the Setting icon)
- Select the activity you want to display on full page
- now share your activity on FB from here.
You will finally see the map with your route highlighted, instead of the boring Garmin logo.
So we're not at the level of Runkeeper, but Garmin is finally doing 'something'.
