Here’s a kewl web-site. You track your mileage with a transcontinental virtual trip across the United States. Each time you enter your mileage, it gets added to your total and it shows you exactly what you would see if you had been traveling from Yorktown, Virginia to Florence, Oregon. For example, if you ran two miles one day, walked four miles the next, and cycled six miles on the third day, you would see the views at 2, 6, and 12 miles west of Yorktown on days one, two and three. The web-site also provides a map that shows your progress and the progress of any virtual running partners you may have. http://exercise.lbl.gov/index.html
