Head over to G-map to find a neat tool. The G-map tool will allow you to map your run or walk using Google maps (at street level) to figure out the exact distance you travel on your morning run/walk. It even has a calories burned tool added on. I found out that the morning walk I take, which I thought was 1 mile long, was actually 1.56 miles. And here I was thinking I was running 20 minute miles.
