Cycle/Run/Walk Across America
Berkeley Lab has designed a transcontinental virtual trip across the United States. Each time you enter your mileage of either running, walking or cycling, they add it to your total and show you exactly what you would see if you had been traveling on the TransAmerica Trail from Yorktown, Virginia to Florence, Oregon. They also provide maps that show your progress and the progress of your friends if they have an account. If you wish, you can form teams to race across the United States.
