After she won the overall World Cup on the 1500 m course in 1989 and gold in the all-round at the World Championships in Calgary in 1990 , Börner threatened to end his career prematurely just eight months later. In August 1990 she was hit by a car while she was cycling, causing a broken foot and cruciate ligament as well as head injuries. After several rehabilitation measures , she reached two second places in the German championships in the 1500 m and 3000 m in December 1991 and qualified for the Winter Olympics in Albertville . There she achieved the greatest success of her career with the gold medal over the 1500 meters and was then awarded the silver bay leaf .
In 1997, the trained banker Börner ended her sporting career without having won a national championship title. A year later she became the head of the speed skating department at the Berlin TSC .
