I am trying to walk more since about mid-December in an effort to get some of my weight off. We used to have a route that was almost exactly one mile, but now I find that I have worked up to being able to do 2 miles with about the same amount of effort. This has caused me to expand my routes to check out parts of the neighborhood I don't normally see.
The graphic at left is from a great web application, Gmap Pedometer. Gmap mashes together software to measure routes with Google maps. It automatically will calculate the total distance, provide mile makers and even give a rough calculation of calories burned.
