For all the years that I’ve been watching the Boston Marathon festivities from my living room armchair, I’ve felt something uniquely simple about each runner crossing the finish line. Oh, I know that the training and the running is incredibly complex, but as the runners turn the corner from Hereford Street to Boylston, there is a simplicity, a floating through the final hundred feet. They are ‘in the zone’, with something beyond themselves carrying them forward. I wonder if I will ever sense that again.
