Heat training has evolved from pre-race survival tactic to sea-level altitude alternative, delivering Hbmass gains, VO?max improvements, and hot-weather resilience with less logistical hassle—here’s how it compares to altitude and when to use each.

Heat might be one of the most powerful—and misunderstood—stressors endurance athletes face, limiting performance by competing with the cardiovascular system’s ability to deliver oxygen to working muscles. This article explains how the body responds to heat, why performance declines, and how targeted heat exposure can drive meaningful adaptations in thermoregulation, blood volume, and aerobic capacity. Used deliberately, heat training becomes not just a way to survive in the heat, but a tool to improve performance in all conditions.
Uphill Athlete Coach Martin Zhor explores how the training principles used by Norway’s world-class Olympic endurance coaches can be applied to mountain athletes, ultra runners, and endurance enthusiasts. He highlights practical strategies for building a strong aerobic base, managing intensity, optimizing recovery, and adapting training to real-world conditions like altitude, terrain, and environmental stressors.
Coach Martin Zhor a structured, six-month training plan to prepare climbers for Aconcagua’s extreme altitude, heavy pack carries, and cumulative fatigue, emphasizing aerobic endurance, strength, and mental resilience. He also offers practical advice on acclimatization, avoiding common mistakes, and building the durability needed for high-altitude success.
