As noted on our sister site AppShopper yesterday, Nike has released a new Nike+ GPS application into the App Store, offering iPhone users new tools for tracking their running performance.

While the Nike+ system built into the iPhone and other devices has required that users purchase a separate sensor to be attached to the user's shoe for tracking, the new application takes advantage of the GPS capability and accelerometer built into the iPhone to provide map-based tracking, as well as pace, and distance traveled. The app also supports challenges, voice feedback, and 'PowerSong' integration to help runners push themselves even further.

Nike+ GPS, which is priced at $1.99, is compatible with the iPhone 3GS and iPhone 4, as well as the second-, third-, and fourth-generation iPod touch, although without the mapping capabilities that require GPS functionality.
