When you plan a route, the first step is normally out of your front door. Take a walk through the neighbourhood you have in mind, and listen to the story it wants to tell.
A route should take the average person at least 15 minutes to walk. It can be longer of course, and most routes are, but when you decide on the length of your route, consider the amount of talking you’ll have to do. There can and in most cases should be silences along the way, and you’ll probably average out at about 100 words per minute of walking. A 15 minute walk works out to roughly 1,500 words, for example, and a 30 minute walk is closer to 3,000 words.
