We spend a lot of time obsessing over VO2 max and threshold pace when we are fresh. But those numbers mean very little at mile eighteen of a marathon. The true currency of a distance runner is durability, which exerci…

In a physiology lab, rested athletes put up beautiful numbers. We measure VO2 max, lactate threshold, and running economy on fresh legs, and those metrics look great on a clipboard. But mile twenty of a marathon does…
