Scotland’s Commonwealth Games 10,000m champion Eilish McColgan has withdrawn from next month’s London Marathon because of a medical problem.
The 31-year-old has had reactions to fuel intake during long practice runs.
The problem has been identified as rebound hypoglycemia, which affects endurance athletes and results in reduced blood sugar levels.
McColgan is now hoping to make her London Marathon debut next year.
“When I run my first marathon, I want to be in the very best condition,” said McColgan, who is competing in The Big Half in London on Sunday.
“When we started preparing for London earlier this year, it was clear that something was wrong with my long runs.
“Refueling in a marathon is such an important part of running to run properly, so I practiced this during my long runs and very quickly I started experiencing bouts of dizziness that really got to me.
“I was relieved to learn that this is not uncommon in athletes. I am grateful to have a truly supportive team around me working to find a solution to this issue and I am confident that we will have done so in time to properly prepare for the 2023 London Marathon. “
McColgan’s mother, Liz, won the 1996 London Marathon. This year’s race takes place on Sunday 2nd October.
