My entries as of late are making me look like a regular Google fangirl. But I can’t help that people keep creating cool apps with Google APIs, and I have to pass them on. My latest find is GMaps Pedometer. GMaps Pedometer uses Google’s mapping functionality to record distances travelled in running or walking workouts.
Basically, zoom into your area and start recording. Double-click points along your workout path and GMaps Pedometer will highlight your path and keep a running total of distance travelled as well as the distance between legs (points) on your path.
