So you run and aren't quite ready to tackle a marathon, but are looking for a race to run. Have I got an event for you. You can participate in the largest, most unique worldwide 10K race — the Nike+ Human Race [1]. It takes place on August 31, 2008, and there are two ways you can run. Either sign up to run in one of the 25 designated race cities [2] including New York City, Los Angeles, Paris, Madrid, or London. Or you can opt to run wherever you are [3] — on a treadmill, on the road, or in the woods. Just track your "race" using either the Nike+ iPod Sports Kit (if you like to run while listening to your iPod nano), or with the Nike+ SportBand [4] (if you don't have a nano). After the race, connect either your nano or the SportBand to your computer to upload your race data to the NikePlus.com [5] website.

All you have to do is register here [6]. If you're running in one of the 25 race cities, the registration fee is $35 ($5 goes towards one of three charities you choose: The Lance Armstrong Foundation, The UN Refugee Agency, or World Wildlife Fund). If signing up for a race has been on your mind, all I have to say is, "Just do it." Imagine running in a global race with a million people – talk about a powerful experience.
