Have you ever been in a marathon? I haven’t. I don’t run very fast, and I haven’t raced against anyone in the past. I like to watch all kinds of marathons. I believe they are of interest to many.
Running the distance can be running across the continent, and meeting people from each town you come to with the agreement that you will finish in so many months. It is a marathon that spurs people to come out to cheer the runners at the end of the race.
