As long as my heart's still in it, I'll keep going. If the passion's there, why stop?...There'll likely be a point of diminishing returns, a point where my strength will begin to wane. Until then, I'll just keep plodding onward, putting one foot in front of the other to the best of my ability. Smiling the entire time.
The Tarahumara would party like this all night, then rouse themselves the next morning to face off in a running race that could last not two miles, not two hours, but two full days. According to the Mexican historian Francisco Almada, a Tarahumara champion once ran 435 miles, the equivalent of setting out for a jog in New York City and not stopping till you were closing in on Detroit.
Every run is a work of art, a drawing on each day's canvas. Some runs are shouts and some runs are whispers. Some runs are eulogies and others celebrations. When you're angry, a run can be a sharp slap in the face. When happy, a run is your song. And when your running progresses enough to become the chrysalis through which your life is viewed, motivation is almost beside the point. Rather, it's running that motivates you for everything else the day holds.
