Hi all! I'm sorry if this has been asked, I did search the forums but didn't find anything. I currently am training for a marathon (one of my New Years Goals). I have my iPhone on an armband while I run, however it is tedious to try and look at it to see my pace, distance, time etc. I was looking at different GPS running watches, but I was curious if anyone here has used an AW for running long distances, and if so, how reliable was it, does the battery last the duration of a long run while using an app such as Nike Running? Any thoughts/feedback on it would be appreciated! Edit: Is the Apple Workout app, which I see from videos on the Apple website has options for indoor and outdoor run, work well enough for pace and distance? And, does it use GPS from your phone, or can I use that app without needing my iPhone on me?
