Nike+ running coach feedback

RoyalMoose11

Looking for opinions in the nike+ running coach using the iphone app. I used Asics My Run app for my first 13.1 because I liked that I could tell it if I wanted to run 3, 4, or 5 days a week and could adjust the days I ran (based on my hockey schedule). I use the nike+ running app already when I run so it'd be much easier but I don't like that I can't adjust how often a week I run. I don't thinks inning 5 days a week will work (well/ maybe when spring and summer comes but it's too cold now).

Have people enjoyed the nike+ coach? I'd like it if, during speed work, it told me when to speed up and slow down (My Run doesn't).
