For those of you who do a lot of walking and record your results this might be something cool for you to do.
I am an avid hiker and a person who hiked the 2650 mile long Pacific Crest Trail created a website here:http://www.walking4fun.com/
What you can do is take your recorded walking and it will tell you how far you would have made it along the PCT. He also took a picture each day he was on the trail and you should get a scenic view showing where you are theoretically at.
Pain is a by-product of a good time.
