Do you walk or run and want to know how far you usually go?
This is cool. You enter your State and City and it brings up a Google map. Zoom in as necessary and find your starting point on the map. Tthen on the left side click "Begin recording".
Then you click on your starting point on the map. Follow your route clicking on the map every few blocks as you go. The total will add up on the left side while you follow your route all the way to the destination. It will show you the total miles that you would go on that route.
