Go the Extra Mile for Critically Ill Babies and Children
Every year, over 2,000 critically ill babies and children are treated in the Neonatal and Paediatric Intensive Care Units at St Mary’s and Queen Charlotte’s Hospitals in London. COSMIC (Children of St Mary’s Intensive Care) supports these children, their families, and the dedicated NHS teams who care for them.
By running the TCS London Marathon 2025 with Team Cosmic, you’re not just taking on 26.2 miles – you’re helping us go the extra mile for families facing the unimaginable.
“The care we received from the team was incredible. Thanks to Cosmic, we could stay close to our baby and be there every step of the way.”
– Charlotte, mum of Seth, a PICU patient
