Because I am an obsessive runner.

Got a athletic gadget geek on your gift list? The Nike+iPod Sport kit is a great stocking stuffer, and an ever greater addition to the (Red)iPod Nano you just bought said athletic gadget geek. Another idea? There is nothing more encouraging to a new excersize regieme than tricking yourself out with super cool gear to hype you up and get you working it out. (via gordon)

Nike and Apple have created Nike + tech which combines pedometers and ipod nanos. the Nike+ system consists of Nike + kit which is a litte extension that clips onto the bottom of your nano and a small sensor that fits in a special slot in select Nike + shoes. The sensor keeps track of how far your run and your time, the nano displays the results. The system is really easy to use and works amazingly well (though I wish it would count steps, not just guestimate distances since I run in the hills so the distance calculations are not going to be as accurate). It also estimates calories burned based on sex, age, and weight. Very cool. And you get to choose your own music and even a "power song" for when you really need to get fired up. A running essential

The Nike + iPod is the greatest invention to running since nike put the waffles on the bottom of shoes. I love being able to know my pace, distance, time and calories burned at the push of a button while I am running. (via paragonsports.com)

Transforms your ipod into a personal jogging trainer and tracks your progress.

I had started running only a few weeks before this was available and I was getting to a stage where I felt I may have stopped running as I lackedthe motivation. Then I found out about this and I love it, I run 4 times a week now and I am able to keep track of my distances and my speed which is great motivation. On top of that I have also been able to take part in a challenge and I have a goal of running 50km in 4 weeks, and the Nike website lets me see how I'm doing.

This great cheap little product gives me a great insight into the speed of my workouts as well as distance which can be hard to determine out on the trails!
