11-year-old to run first marathon in aid of Cystic Fibrosis inspired by her godfather’s baby boy
An 11-year-old from Northampton will soon run her first marathon in aid of a worthy Cystic Fibrosis charity, and she was inspired to take on this challenge by her godfather’s baby boy.
This is Brontë McGrath’s second fundraiser for the Cystic Fibrosis Trust. Her marathon, taking place at the end of the month, will begin at Milton Keynes parkrun and end at her home in Northampton.
Brontë’s godfather’s son was born more than two years ago with the condition and she also has a friend at parkrun who lives with Cystic Fibrosis, which is why the 11-year-old is so passionate.
Cystic Fibrosis is a genetic condition which causes sticky mucus to build up in the lungs and digestive system, which affects more than 1,000 people in the UK and one in 25 carries the gene that causes it – usually without knowing.


It comes with its challenges, including impacts on physical health, mental wellbeing and how people choose to live their lives, and Brontë is one of many uniting towards the ultimate goal of effective treatment for all.
Brontë’s mother Kate McGrath spoke to the Chronicle & Echo and shared that her daughter’s first fundraiser took place in March 2024, when she ran 75 miles throughout the month.
The 11-year-old attends Northampton Athletics, does parkrun most weekends and plays netball, but this will be her first ever marathon.
Brontë has already raised more than £2,000 and Kate said: “She makes me so proud and I love her to bits. She’s always smiling and resilient. We tell her to enjoy it more than anything as this is such a big thing.”


An impressive amount has already been raised for the worthy cause, as a result of the support from family, friends and those who continue to champion Brontë from parkrun.
“Everyone is behind her and we’re already blown away by the support,” Kate concluded.
