Year 13 pupil Zac Priest, along with his father Tim, are taking part in the race on behalf of the Momentum Children’s Charity, a non-profit organisation which supports families of children facing life-challenging conditions in London, Surrey and Sussex.
Three-year-old Theo was diagnosed in July 2021 and has had to undergo months of chemotherapy.
Zac said: “When Theo was diagnosed it was hard for all of us and going for a run was an escape for me. So I thought, why not sign up for the marathon and benefit the charity that has helped us so much?”
Luisa Priest, Zac’s mum, commented: “As soon as Theo was diagnosed, Zac said he wanted to do something to help: we’re all really proud of him. Theo has had to have a lot of general anaesthetics for lumber punctures and lots of chemotherapy. He still has chemo everyday but it’s now in the maintenance stage, so things are better.”
Paul Foster, Warlingham School's head teacher, said: “We are so proud of Zac and his determination to fundraise for such a worthwhile cause. He truly embodies our school’s values of courage, commitment and kindness, and is an inspirational role model for our students.”
