OC Harriet Runs the TCS London Marathon

OC Harriet Onions (2024) undertook the incredible challenge of running the TCS London Marathon on Sunday, 27th April 2025. She proudly ran in support of Demelza, a children's hospice dedicated to providing vital clinical care and emotional support to babies, children, and young people facing serious or life-limiting conditions across East Sussex, Kent, and South East London.

Thanks to Harriet’s dedication and the generosity of her supporters, she raised an impressive £2,076 for this wonderful charity. Harriet would like to extend her heartfelt gratitude to all the Old Cornelians for their incredible support and encouragement throughout her journey.
