Notable to me is the word "National." Most countries don't need a Walking Day to get their citizens up and moving. In many parts of the world, if you don't walk you don't work and you don't eat.
I see no need to extol the benefits of walking more today than other days. There's a reason why I named this blog A Walker in the Suburbs. But I will point out that in one of my favorite cities in all the world, walking is not just popular on National Walking Day but all year long.
New York City is a walker's paradise. It's the place Alfred Kazin describes in A Walker in the City, to which this blog tips its hat. It's no coincidence that lively walking cities are lively cities, period.
There is something about a human that loves a walk. And what better day to remind ourselves of that?
