Nike+ Challenge Widget lets you check your challenge ranking beyond your browser, any time. See when your competitors sync runs and keep motivating yourself to top the leader board. You'll log in securely with your Nike+ info to load your challenge(s). Pressing control-R will refresh the score.
Together, Apple and Nike created Nike+ to change the way we run. A sensor in your Nike footwear talks to a receiver connected to your iPod nano, and they mutually track the details of your runs. You'll know your distance, pace, calories, and time, every stride.
