Apple Nike + iPod Sport Kit

Use the Apple Nike + iPod Sport Kit to track your workouts, set goals and keep the rhythm going. The kit comes with a sensor to put in one of your Nike+ shoes and a receiver which connects to your iPod nano. iPod touch and 3GS and later models of the iPhone include built-in support for Nike + iPod, so there's no need to use the receiver with those models.

The Sport Kit can also be used at the gym for tracking your workout with Nike + iPod compatible cardio equipment. When you're all done working out sync your iPod to your Mac or PC. Your computer and iTunes automatically send your workout info to nikeplus.com for a number of ways to gauge your progress and connect with other runners and challenge friends.
