EP 736: Unlocking Endurance from the Neck Up

Trail Runner Nation

In this episode of Trail Runner Nation, cognitive neuroscientist and endurance athlete Dr. Scott Frey reveals how brain training can unlock new levels of performance for trail and ultrarunners. He explains that while most athletes focus on the physical, it’s often the brain that sets the limits—through perceived effort, cognitive fatigue, and pain signals. Dr. Frey introduces his Brain Endurance System Training (BEST), a method that combines cognitive and physical training to build mental strength and resilience. We talk about managing cognitive load, how the brain predicts fatigue, and why a mental taper can be just as important as a physical one. Listeners will learn how to train smarter, race longer, and enjoy the sport deeper by understanding the true power of the brain.
