*Updated 6/29/2009* Only the Nike+ sensor is required for use with the iPhone, not the entire Nike+ Sports Kit.
Apple has announced that the next generation iPhone 3GS will have built-in support for the Nike + Sports Kit Nike+ sensor, a system that allows runners to track and record the speed and distance of their walks or runs.
The Nike + Sports Kit comes with a sensor that fits into the sole of specially designed Nike+ shoes or can be attached to the shoelaces of other brands of running shoes. An accelerometer in the sensor measures the pace and distance of a run, and sends the information wirelessly to the iPod or iPhone. Previous versions required that a receiver be plugged into the bottom of the iPod in order to receive information from the sensors, but Apple’s announcement of “built-in” support may hint that the receiver will no longer be necessary.
The Nike+ system also integrates with a special Nike website that allows runners to track and compare their workouts with other runners around the world. It’s likely that the iPhone version of the app will bypass the need for connecting to a computer to upload your running data to Nike’s website.
Nike + also comes with other features that can enhance workouts, such as a Power Song that can be instantly played for some extra motivation and congratulatory recordings from athletes like Lance Armstrong, Tiger Woods, Joan Benoit Samuelson, and Paula Radcliffe that play if a runner achieves a personal best in various categories (fastest mile, fastest 5k, etc).
Another recent addition to the Nike+ system is Nike + Workout. The new feature allows your iPod to connect with compatible Life Fitness cardio equipment, a popular brand found in many health clubs, and track and record your workout. An example an iPod connecting with Nike + Workout-compatible Life Fitness equipment can be seen below:
The iPhone 3GS will be available in stores June 19. No date has been announced for the Nike+ iPhone app, but the Sports Kit Nike+ sensor is available in stores now.
