In the past thirty years, I’ve run thirty-three full marathons. I’ve run marathons all over the world, but whenever someone asks me which is my favorite, I never hesitate to answer: the Boston Marathon, which I have run six times. What’s so wonderful about the Boston Marathon? It’s simple: it’s the oldest race of its kind ; the course is beautiful; and?here’s the most important point?everything about the race is natural, free. The Boston Marathon is not a top-down but a bottom-up kind of event; it was steadily, thoughtfully crafted by the citizens of Boston themselves, over a considerable period of time. Every time I run the race, the feelings of the people who created it over the years are on display for all to appreciate, and I’m enveloped in a warm glow, a sense of being back in a place I missed. It’s magical. Other marathons are amazing, too?the New York City Marathon, the Honolulu Marathon, the Athens Marathon. Boston, however (my apologies to the organizers of those other races), is unique.
