This is a thing! You record how much you walk/run/hike/bike/swim and compare it to the journeys in Lard Of The Rings!http://home.insightbb.com/~eowynchallen ... /walk.html
In the Fellowship of the Ring, by J.R.R. Tolkien, Frodo, Sam, and their companions travel from Bag End in Hobbiton to Rivendell. Our goal is to re-create their walk in our neighborhoods, parks, gyms, homes, and minds.
Walk, run, hike, bike, blade, swim - if you can measure the distance, you can do this challenge. Keep a log, and record your daily or weekly miles and the type of exercise. For walkers and hikers, you might want to invest in a walking meter, they look like wristwatches. Otherwise, you can estimate your distance at 1 mile for every 20 minutes of brisk walking on a flat surface.
I just about nerdgasmed when I heard about this earlier. And its kinda sad that it takes a Tolkien reference to get me interested in exercising.
