A few years ago, my mom led a walking challenge at work and everyone loved it. I was checking out the website and there are a number of options like 'Walk the Appalachian trail" and "Walk Across America" where you enter your daily steps (and step equivalents if you do things like yoga that don't involve an actual step count). It shows you how far on this "journey" you have walked up to this point. Anyone interested?
