It inspires people to transcend themselves and attempt new and difficult challenges. It's a positive force in a cynical world. Nor will the video or photographic evidence prove it. This sort of evidence can easily be produced with the aid of a car or bicycle. Likewise, media coverage is not worth very much.
Most reporters have little or no knowledge of distance running, let alone journey running.
They are easily duped - as you have demonstrated so clearly. Your idea, as Tom Claytor said, is brilliant, a lone man running around world, redefining aerobically the goal that has inspired all great explorers from Columbus to the modern-day astronauts. But that is academic given what we know to date about your run. Dave Kunst is an obvious example. Because there are many runners who have run farther than the total accumulated mileage that you are claiming, and some have done a good deal of it in foreign countries.
