Answer
The World Marathon Record set by Paula Radcliffe in 2003 stood unbroken for 16 years until Brigid Kosgei shattered it in the 2019 Chicago Marathon. Kosgei crossed the finish line in an astonishing time of 2:14:04, surpassing Radcliffe's previous record by 81 seconds. This momentous feat marked a new era in women's long-distance running and cemented Kosgei's place in the annals of athletics.
