A two-mile grass loop through 120 acres of forest and open field, run under a cutoff that gets one minute shorter every single lap. Forty-five minutes for the first. Fifteen for the thirty-first. Seven laps is a half marathon, fourteen is a marathon, sixteen is a 50K, twenty-five is fifty miles, and thirty-one is 100K. The clock decides when you are done, not you.
