Hello, I wonder why doesn't the 955 offer this option? With the Instinct 2 there's TracBack for a previous activity. For courses its possible to navigate them in reverse order. But for activities it's not possible. You must first save as a course, which requires Garmin Explore and then navigate the course in reverse. Which for some reason didn't work for me in the backcountry (without internet) and it ended up on a sync loop, leaving me no option other than just looking at the activity track on the map without using the navigation features. Any ideas?
