Baker was born in Ipswich, Suffolk, England and was a member of the Coventry Godiva Harriers. A talented junior, she won the AAAs National Under 15 800 metres title in 1978 and the Under 17 title in both 1979 and 1980. In 1981, at the European Junior Championships, she finished fifth in the final in 2:07.39. She represented England at the 1982 Commonwealth Games in Brisbane, finishing sixth in 2:03.17. At the 1984 Los Angeles Olympics, Baker was the only British representative in the women's 800 metres. She excelled herself by reaching the final, placing fifth in a personal best of 2:00.03, just failing to break the two-minute barrier. Having come close to breaking the two-minute barrier on a number of occasions, Baker at last succeeded at the Crystal Palace, London in July 1986, when she ran 1:59.99. This made her only the fourth British woman in history to run sub 2 minutes for the 800 metres, after Christina Boxer, Shireen Bailey and Kirsty McDermott. Two weeks later at the Commonwealth Games in Edinburgh, she won the bronze medal in the 800 metres final in 2:01.79, behind Kirsty Wade and Diane Edwards. In August, she achieved her lifetime best of 1:59.67 at the Berlin grand prix. Two weeks later at the European Championships in Stuttgart, she reached the semi-finals and ran 2:02.03. Baker then suffered two years of injury problems, before returning to form in 1989 and gaining selection for the 1990 Commonwealth Games, held in New Zealand in January. In Auckland, she finished fifth in the final in 2:01.77. A month later, at the 1990 European Indoor Championships in Glasgow, she ran 2:02.42 to win a bronze medal behind Lyubov Gurina of the Soviet Union and Sabine Zwiener of West Germany. She continued as one of Britains most consistent 800 metre women for the next two years. At the 1991 World Championships in Tokyo, she reached the semi finals running 2:01.32. In 1992, she qualified for her second Olympics. In the heats of the Barcelona Games, she ran her best time for six years, with 2:00.50, to reach the semi-finals, where she ran 2:02.17. Barcelona proved to be the conclusion of her international career. Throughout her career, Baker placed second or third 15 times at senior national championships, without ever winning. At the AAA Championships, she was second three times, at the UK Championships she was second three times and at the AAAs Indoors, she was second twice. As of 2018, her best ranks 17th on the UK all-time list. Her best as a junior still ranks fourth on the UK Under 20 all-time list. She also ranks sixth on the UK all-time list at 1000 metres with 2:35.51.
