For general reference, for those of us who like to map out and know distances of our walking, running, hiking, whatever routes Google Map Pedometer is a cool tool. You can pull up a map of your neighborhood, connect points along the route you walk and it will give you the distance and if you enter your weight it also calculates the number of calories burned. A favorite walking loop of mine, which I just came from a brisk stroll in this dark and misty night, is 2.12 miles around the streets of my neighborhood. link c/o Mark's del.icio.us page
