The Watch isn't out yet in my region (I will hopefully be able to buy mine this friday), so I've no way to check this myself, but hopefully someone will know some answers... Anyway, here goes: I'm not built for heavy exercise, but I like to walk, sometimes quite long walks of an hour and a half or more. From what I've read, exercise tracking seems to drain the battery fairly heavily, how would it fare over such a long walk? Is there even a hiking exercise program built in? Can you just start a walk and then have it run an arbitrary time/distance, or must you set a time duration prior to starting? I might not know how far I want to walk before setting out... Also, is there a feature in the Watch that can track your route, distance walked, and show it on a map afterwards perhaps? Thanks for any input!
