I’m trying to get into shape. Break out the Wii Fit, my Asics, and my iPhone. Today was a 4 mile walk. I mapped my walk using an iPhone app called MapMyWalk – it does runs and rides too. Pretty darn accurate too - I used my pedometer just in case and the results were identical. You can track your walks/runs at their website MapMyRun.com and then share it with friends via the standard virtual networks.
