Over the next 30 years, Liz reached the top of her game. Highlights included an Olympic silver medal at Seoul in 1998 and a second Commonwealth gold in Auckland in 1990, both in the 10,000m. Other victories included golds at the 1991 World Championships in Tokyo and the World Half Marathon Championships in Newcastle in 1992. She also claimed silvers at the World Cross Country Championships (1987) and World Indoor Championships (1989).
In 1991, Liz was named BBC Sports Personality of the Year and in 1992 was awarded an MBE. Four years later, she won the London Marathon, finishing as runner-up the following year in her career-best time.
She retired from competing in 2001 after fracturing a bone in her foot, but made sporadic appearances over the next 15 years. The eldest of her five children, Eilish, is now an accomplished long-distance runner who is a double European medallist and a three-time Olympian.
