About Virtual Walk
"To keep themselves motivated, some walkers keep track of their accumulative miles on a virtual map across the country. Virtual Walk is an Android app that is based off that simple concept. Instead of mapping out where you are, (MapMyWalk and Endomondo are examples that do this), Virtual Walk maps out where you want to be - on a map chosen from an expanding library of virtual routes.
Each route has something different to offer, and they vary from lengthy treks (Appalachian Trail) to historical tours (Washington D.C.). Interesting information about landmarks that users “walk by” is included along the way. The content is rich and contains pictures, to give users as much of a feeling that they are actually there as possible. There are also quizzes and links to YouTube videos to make things even more interesting.
The goal of Virtual Walk is to provide these virtual experiences, while maintaining motivation and fitness details that a walker needs. Each walk is recorded along with miles and time to be reviewed later. The support for Virtual Walk is ongoing, and new features and routes will be added frequently."
You can also feel the achievement of walking the length of the Appalachian Trail without the need to carry a backpack and use trekking poles (although you may want to do that for authenticity!) The screen shots also show a virtual Boston Marathon, which is probably the only way a walker will be able to do the race, due to the qualifying times.
The app is currently only available for Android. I haven't found any similar app for iOS.
