In front of 30,000 people at the Alexander Stadium, McColgan pushed past the Kenyan Irene Cheptai to take the gold medal in the 10,000m - the same race her mum, Liz, had won gold for Scotland at the 1986 and 1990 Commonwealth Games.
Not only did McColgan win her first major gold, she also recorded a games’ record for the 10,000m, completing the race in 30mins 48.60 seconds.
McColgan’s win is even more impressive given the Scottish runner had to endure seven weeks out with Covid, further illnesses and minor injuries in the lead up to last month’s World Championships where she finished 10th.
Speaking after her win, McColgan said: “My family were here, the crowd on that last 100m, well it was vibrating through my own body.
“Without the crowd, I wouldn’t have finished that. I wanted it so badly.
“I know the girls were super strong. But I knew if I could stay with them I had a chance of a medal. This is an absolute dream”

After winning a silver medal in the 5000m at the UK Outdoor Championships, and the gold medal in the 1500m at the 2011 Scottish University Championships, McColgan qualified for the 2012 Summer Olympics steeplechase.

Eilish McColgan in 2022
February 2022 saw McColgan set a new British record in the 5km road race, hitting 14.48 in Dubai, breaking the record set by Paula Radcliffe in 2003 and bettering her mother’s own unofficial record of 14.57 in 1991.
McColgan then went on to beat Radcliffe’s 21-year-old British half marathon record by 12 seconds, completing the course in a time of one hour, six minutes and 26 seconds.
Paula Radcliffe’s 10km record was then smashed at the Great Manchester Run by McColgan who finished the race in 30 minutes 19 seconds.
The Scottish 31-year-old finished second, behind Hellen Obiri.
After coming sixth in her other races at the Commonwealth Games 2022, McColgan finally won her first ever major gold at the women’s 10,000 metres, achieving a games record in the meantime.
McColgan outside the track

The aim of their organisation, Giving Back to Track, is to encourage young people to get involved in athletics and to fund the next generation of female athletes.
