This episode dissects the absolute limits of human endurance, revealing the brutal physiological cost of maintaining a 21.1 km/h pace: a sustained oxygen uptake of 67 ml/kg/min at 94% of VO₂max. We go beyond the classic triad of endurance to explore the fourth dimension: physiological durability. Discover how running economy degrades over two hours, how a metabolic shift to fat oxidation can increase oxygen cost by 30%, and how computational fluid dynamics (CFD) prove that "swordfish" drafting formations can save over four minutes. We'll also analyze the technological arms race, from World Athletics' 40mm stack height rule to the disposable, sub-140-gram hyper-shoes changing the game. Finally, we translate this elite science into your training. Learn why a negative split strategy is almost always superior, how you can leverage drafting in your own races, and why building musculoskeletal durability is far more critical for marathon success than chasing a higher VO₂max. This is the definitive blueprint for the sub 2-hour marathon.Keywords: 2-hour marathon, marathon, running, endurance, vo₂max, running economy, aerodynamics, kelvin kiptum, hyper-shoes🎙️ Lactate, the podcast that deciphers science to improve your performance.Key references :Jones, A.
