Scott Johnston's Winning Formula for Ruth Croft and Tom Evans at UTMB — Season 7 Ep 10
Scott Johnston, fresh off coaching both the men's and women's winners of UTMB in the same year, shares his coaching philosophy with Dirk Friel. Scott emphasizes the value of consistent, disciplined training rooted in tried-and-true principles. Not through flashy shortcuts, just a thoughtful blend of science, individualized pacing, and real-world adaptability.
Throughout the conversation, Scott explains how he tailored training for Ruth Croft and Tom Evans, highlighting that while every Evoke Endurance training plan is built on a shared set of core principles, the real magic lies in personalizing workouts to each athlete's unique needs and life circumstances. Hear how Scott's approach balances rigorous data—like lactate testing and measured thresholds—with the all-important "soft" skills of daily check-ins, building trust, and keeping athletes mentally anchored during major events.
One clear takeaway: success is less about pushing past your limits at every session and more about knowing when to hold back, adapt, or shift focus. Scott also dives into the technical side: steep treadmill sessions to build fatigue resistance, the smart use of poles, innovative altitude and heat strategies, and the power of true athlete-coach communication.
