Nike+ Who does it?
 

Anyone else doing Nike+? I want to compete with some friends. Only have a couple of local buddies that are doing it.

I don't even know what is it... :pimp

the other day i´ve bought the sensor for my shoes and the same day i´ve noticed that you can download the "nike+ gps" app for free for your iphone and don´t need the sensor :o/ .
but i had no chance to try it yet,i´ve walked a bit and it gives a feedback but it was not enough to give you the right answer.
but i think the nike+ gps is the one you should use for copeting with friends,it has some extra features.
sorry for not being helpful!

chip that ass
