Join 16,000 runners for one of London’s most scenic half marathons. This stunning 13.1‑mile route takes you past some of the capital’s most iconic landmarks on fully closed roads and through four of London’s Royal Parks — Hyde Park, The Green Park, St James’s Park and Kensington Gardens.
All the while, you’ll be raising vital funds for the AT Society. Every step you take helps us drive forward essential research and ensures that children and young people with AT receive the specialist care and support they need.
