I've had the original AW since April but, as a runner, knew I might sell it and upgrade to Series 2 if it included onboard GPS. While I always carry my phone with me (mainly for music), I've had some inconsistencies with pace and distance with my AW 1, and that continued today when I did the Bronx 10 Mile and had Runtastic's measurements off by .3 miles too much and faster by 13 sec/mile. I expected to be a little off, but that seems a little high to me.

Have people found the GPS on Series 2 more accurate than the first version? I'm considering switching so I can get more accurate stats during training runs and races. I know Series 2 uses the phone's GPS unless you don't run with a phone, but I'd just put my phone in airplane mode while I'm running. Thoughts?

By which you actually mean, have people found the GPS on series 2 more accurate than that of the iphone, no?

I assume that was the point. Wasn't there some talk about how the AW2 would use the phone's GPS if it was paired as the phone's is more accurate?

Yes it uses the GPS from the phone whenever possible. But that's mostly to save battery.
