From Skeptics to Scientists: The Far-Reach of Average Marathon Times When the first long-distance runners took to the roads in the late 19th century, their grueling 40-kilometer (25-mile) races sparked more than just athletic pride—they ignited decades of skepticism. “Can humans actually complete such distances?” critics questioned. “Isn’t this just a spectacle for showmanship?” Yet over time, average marathon times have evolved from controversial benchmarks into powerful scientific indicators, transforming how researchers, athletes, and medical professionals understand human endurance, performance, and health. ### The Skeptical Beginnings: Marathons Were Dubious at First In the early days, the marathon was met with doubt and resistance. The idea of running 26.2 miles—then increased to the modern standard in 1921—seemed almost supernatural. Skeptics argued that such distances pushed physiological limits and invited injury, fatigue, and abandonment. Yet as marathon times slowly improved, so did the credibility of these extraordinary feats. From skeptics emerged early advocates and scientists keen to decode the physiology behind these long distances.
