While competing for the AAA Indoor Championships, Murphy was in her third year of law at Brunel University.
Murphy was daunted to focus on the 400m over the 200m, but the events were too close to each other during the World Indoor Championships to compete in both.
[9] She hoped to medal in the 400m at the 2002 Commonwealth Games since her rival Katharine Merry was injured,[10] but finished sixth in the final.
At the 2002 AAA Indoor Championships she was unable to try for a repeat of the double due to a change in the event schedule.
[14] At the 2004 Athens Olympics, she again finished fourth in the 4 × 400m relay, along with Donna Fraser, Christine Ohuruogu and Lee McConnell.
The statement prompted the chairman of UK Athletics to send a letter to Great Britain's relay team, congratulating them on their now bronze-medal finish.
