On May 6, 1954, Roger Bannister, a British middle-distance runner and medical student, achieved what was once thought to be impossible: running a mile in under four minutes. Completing the mile in 3 minutes 59.4 seconds at a track meet in Oxford, England, Bannister’s feat shattered physical and psychological barriers, redefining the limits of athletic performance. His accomplishment remains a symbol of determination and boundary-pushing in the realm of sports and beyond.
