Carrying a 50 pound bag of sand on your back for a long stretch might seem like a difficult task until you consider that Atlas, the Greek titan of endurance, was charged with the task of carrying the world and sky on his back for all of eternity. We feel that our runners are getting off pretty easy in comparison. When you pick up the bag and start moving forward remember that each step brings you closer to the finish line. Never give up. Never Surrender.
