From a 5-Hour Marathon to 2:34 in Berlin | Troy Castle’s Work-Ethic Blueprint

How did former SMU football player Troy Castle go from a painful five-hour first marathon to a 2:34 finish at the Berlin Marathon? On DFW Running Talk, host Chris Detzel sits down with the Dallas runner and two-time Irving Marathon winner to explore the marathon training, Ironman endurance base, Boston-qualifying breakthrough, Texas heat preparation, threshold workouts, and relentless consistency behind his transformation. Troy also explains how he balances serious running with three young children, why the Dallas running community changed his training, and what runners can learn from his pursuit of a sub-2:30 marathon.
