Fanny Blankers-Koen

Athletics, Netherlands. At the 1948 London Olympics Blankers-Koen, a 30-year-old mother of two, won the 100 metres, 200 metres and 80 metres hurdles individually, then ran the anchor leg to bring the Dutch team from behind to win the 4x100 metres relay. She held world records in several individual events during her career, and her relay leg showed the same speed under team pressure.
