About Regina Jacobs
Regina Jacobs is an American former middle-distance runner from Los Angeles. She had an extended career that included two IAAF World Championships in Athletics silver medals and an indoor world championship at the age of 39. Three months later, her career ended after winning what would have been a fifth straight National Championship in the 1500 meters when she was disqualified and banned for doping related to the BALCO scandal. Jacobs took second place in the 1500 m race at the 6th World Championships in Athletics in Athens (4:04.63) in 1997, and again won the silver medal in the 1500 m at the World Championships in Sevilla in 1999 (4:00.35). On February 1, 2003, Jacobs set a world record in the indoor 1500 m with a time of 3:59.98, becoming the first woman to break 4 minutes in the event. Months later, she was officially banned for doping but her American record technically stood until March 2, 2025, when Heather MacLean ran 3:59.60 to set a new American record.
