McColgan's 10,000 metres best of 30:57.07 set in 1991, moved her to second on the world all-time list at that time and stood as the Scottish record until 2022, when it was broken by her daughter Eilish McColgan. Her marathon best of 2:26:52 set in 1997, stood as the Scottish record until 2019.
She joined her local athletics club, Hawkhill Harriers, aged 12 on the advice of her PE teacher Phil Kearns[3][4] Coached by Harry Bennett, she soon discovered a talent for distance running and won her first UK titles aged 18.[3] Following Bennett's death, McColgan coached herself in preparation for the Commonwealth Games in Edinburgh in 1986.[3] From 1987 to 1989 McColgan was coached by John Anderson, including at the 1988 Olympics, after which she coached herself to the world 10,000m title and to wins in the London, New York and Tokyo marathons. She then met Grete Waitz, who coached her from 1992 to her retirement in 1996.[3]
In 1988, now competing as Liz McColgan, she improved her own UK record with 31:06.99 in July to defeat Kristiansen in Oslo. Almost three months later, she ran 31:08.44 to win an Olympic silver medal in the inaugural women's 10,000 metres at the Seoul Olympics. She was defeated by the Soviet Union's Olga Bondarenko. McColgan won silver in the 3,000 metres at the World Indoor Championships in 1989. In January 1990, she became the only Scot to successfully defend a Commonwealth title at the 1990 games in Auckland, New Zealand, when she again took the gold in the 10,000 metres, as well as bronze in the 3,000 metres.[2] She missed the rest of the 1990 season due to pregnancy, giving birth to her daughter (future Olympic athlete) Eilish in November. Nike dropped her the moment she told them she was pregnant.[6]
Just six weeks after her daughter Eilish was born, she contested an international 5 km race in Florida and won a bronze medal at the 1991 World Cross Country Championships. In June 1991, she ran her lifetime best for the 10,000 m with 30:57.07 in Hengelo, becoming only the third woman to run under 31 minutes, moving to second on the world all-time list behind Kristiansen and narrowly ahead of Bondarenko. This stood as the Scottish record until it was broken by Eilish in 2022.[7] In August 1991, she won gold in the 10,000 metres at the World Championships in Tokyo, Japan.[8] In November of that year at the New York City Marathon, her first marathon, she won with a time of 2:27.23, breaking the record for a debut marathon by three minutes.[9]
After more than two years struggling with injuries, McColgan finished fifth in the 1995 London Marathon and sixth in the 10,000m final at the 1995 World Championships in Gothenburg. In 1996, she won the London Marathon in a time of 2 hours, 27 minutes and 54 seconds, before finishing 16th in the marathon at the Atlanta Olympics. She finished second in the London Marathons of 1997 and 1998, running her career-best time of 2:26:52 in 1997. She gave her medal to a youngster in the crowd after the 1997 event.[10]
McColgan retired from competing in August 2001 when she fractured a bone in her foot while training for selection for the 2002 Commonwealth Games.[11] However, she returned in 2004 to win the Scottish Indoor Championships 3000 metres (in 9:31). In 2007, she ran the London Marathon, finishing 25th in 2:50:38. She also completed the 2010 New York Marathon in 3:10:54. In 2017, she completed the inaugural Stirling Scottish Marathon in 3:18:32.
Personal life
In 1987 she married Northern Irish athlete Peter McColgan; they had five children together - Eilish, Martin, Eamonn, Kieran and Orla. The couple separated in November 2010 and finalised their divorce in March 2013.[12][13] On 18 January 2014, McColgan married John Nuttall[14] (1967–2023), a coach who worked as head of endurance coaching for British Athletics and later coached in Qatar, becoming step-mother to Nuttall's son, para-athlete Luke Nuttall and daughter, British international athlete Hannah Nuttall.[15]
McColgan's eldest daughter, Eilish, is also a distance runner. Eilish broke her mother's Scottish 10,000 metre record in 2022,[7] and emulated her mother by winning the 10,000 metres at the 2022 Commonwealth Games.
