Thanks to a unique partnership between Nike and Apple, your iPod nano can do more than play music. It can now be your coach, your personal trainer and your favorite workout companion. A small sensor inside the Nike+ shoe communicates with your iPod nano, and your iPod communicates with you. Real-time data, such as running pace, time elapsed, calories burned and distance elapsed, are spoken over your favorite music. You can also track and manage your workout through a dedicated web site that offers goal-driven training programs and graphic results. The web site also allows you to create run-specific playlists, such as mellow songs for your warm-up and cool-down, and more intense tunes for the run in between.
