Ran 3.2 mi today with my Nike+ Running app.
I love this app b/c the GPS is so accurate. However……
Be aware that when you are pulling music from “The Cloud” and you run into a place with delayed service, the running app will pause. So you keep running but the Nike+ app is turned off. . As you run in and out of service the app turns on and off.
The way to alleviate this problem is to leave the playlist on my phone so I can access it directly.
