The 2026 TCS London Marathon set multiple records, including world-class elite performances and the largest-ever field of finishers, while also highlighting an extraordinary age span among participants. The event’s oldest runner, 88-year-old marathon veteran Harry Newton, and its youngest, 18-year-olds Molly Bull-Diamond and Khadija Khalfaoui, embodied the event’s inclusive spirit as all three crossed the Finish Line on the same day.
