I created this over at eGriz.com but I thought that a lot of you would be interested as well. Nike+ is a cool little gadget that puts a chip in your running shoes and connects to an ipod nano. It keeps track of your running stats and allows you to upload them to nike+ website. I created a challenge to see who can run the farthest distance in 30 days starting on June 11th. You can see the results in the widget in the sidebar. If you would like to participate, please click the link in the widget to sign up (it’s free)!
