Have an iPhone? Then you can get the Nike+ GPS app for a few bucks. It will tell you your distance and cheer you up and all you people who try to follow this but get confused by the km-thing- you can set your settings to show you how far a km really is!
I say it worked fine and the runs are really easy to sync.
The Nike+ thing really helped me when I started running. By now, I've run and logged more than 1500 kilometers! Perhaps in a year or two, you will have done the same!
