The Nike+ Sport Kit monitor is one of the coolest things you buy for your iPod if your a runner or, simply, into fitness. Thanks to the release of the iPhone SDK that kit may soon become available for the iPhone and iPod touch.

Consisting of an accelerometer-based pedometer/sensor, which you attach to your sneaker, and wireless receiver that plugs into your iPod, the kit monitors distance, time, pace, and calories burned. Better yet, it displays that information on your iPod's screen and delivers real-time audible feedback through your headphones to keep you informed and help get you motivated.

Whereas current Nike+ users must dock their iPods to upload workout data to their computer, the iPhone/iPod touch version of the kit may take advantage of Wi-Fi—and, you'd think, 3G in the next-gen iPhone—to seamlessly update training logs wirelessly, on the fly.

This would certainly make the system more convienient for those of us who are forgetful but still want to use Nike+ to track their fitness over time.

Perhaps the update to Nike+ will even take advantage of Nike's new Nike+ Coach training system. Already available for the Nike+ SportBand (basically the Nike+ system without the iPod), Nike+ Coach is a motivational system, including Web site) that provides beginning and intermediate runners with access to existing programs to train for a 5k, 10k, half-marathon or full marathon.

No matter what personal coaching program users choose, runners can choose to automatically track and share their results.
