Nike in collaboration with Apple launched Nike+ today. Nike+ is a complete training system to help runners keep track of their runs. The system involves a pair of Nike+ sneakers - the Air Moire, an iPod Sport Kit and the Nikeplus.com website. The system helps runners track their runs and get voice updates of their progress during their runs. After the run, runners can upload their runs to the Nikeplus.com site to log their progress. Because of the web base system, one of the cool things you can do is challange your friends anywhere around the world - run the challange, upload and see who won.
