Walking For Fun and Fitness
Walking4Fun.com which is owned by a letterboxer and hiker. You need a pedometer to keep track of your steps that you make each day. This is free site to use. Each day, you enter the total number of steps you made. You also set it up with your stride length (length between left and right steps as you walk). It then calculates the number of miles you walked for that day. There are a few trails to pick from.
