The Man With a VO2max of 101. Scientists Say It's Impossible

Scientists are calling it the most extraordinary number ever recorded in a human athlete. Others are calling it a calibration error. In January 2026, Kristian Blummenfelt posted a lab screenshot to Instagram showing a VO2max of 101.1 ml/kg/min — a number that would shatter every record in the history of exercise physiology. Within hours, Pogačar's own performance coordinator publicly questioned it. A Nobel Prize-winning framework built in 1923 is at the centre of the debate. And hidden in that same screenshot was a second number — one that makes the whole story even stranger. This is a breakdown of the science, the controversy, and what it actually tells us about the limits of human performance. ━━━━━━━━━━━━━━━━━━━━━━ ⏱ CHAPTERS ━━━━━━━━━━━━━━━━━━━━━━ 0:00 — The number that broke the internet 1:25 — He looks like a rugby player. He's the greatest triathlete alive. 3:29— What VO2max actually is (and why 101 is insane) 5:27 — 🚨 The second number nobody talked about 5:52 — Why scientists are calling it impossible 8:31 — His own coach makes it even more complicated 9:33 — The 100 year old science that still can't keep up 10:44 — My verdict: the number might be wrong. The athlete is not. 12:26 — Next: The coach who burns his athletes' stool samples for data ━━━━━━━━━━━━━━━━━━━━━━ 🔗 MENTIONED IN THIS VIDEO ━━━━━━━━━━━━━━━━━━━━━━ → Kristoffersen et al.
