Today I am going out today on my favorite walking trail: The Sawmill-Branch Trail in Summerville, South Carolina. More info here
It's about 6 miles each way through the middle of Summerville with parking available in certain points. Since I can't yet walk 12 miles, my strategy is to park in the middle to allow for breaks and the ability to walk shorter distances.
Also critical is a very good music selection. I need upbeat, fast-moving music to keep me going. This is where iTunes comes in handy!
