About this episode

The episode discusses the importance of durability and efficiency in endurance triathlon and how to train for these traits.

In this episode we pull back the curtain on two often-underappreciated yet hugely decisive traits in endurance triathlon: durability and efficiency . We’ll explore what it takes to sustain output and hold technique deep into a long race, why your efficiency matters more than you might think, and how you can train the physiology of fatigue resistance. You’ll hear how metabolic, neuromuscular, cardiovascular and brain-effort systems all play a role. We'll view all this through pro triathlete and Working Triathlete coach Mitch Ott’s standout day at Ironman Chattanooga as a live example of these principles in action.
