Royal Parks Foundation Half Marathon 2026

The Royal Parks Foundation Half Marathon is a central London half marathon run in October on closed roads. Its appeal is a traffic-free route past famous London landmarks and through four of the city’s eight Royal Parks, all within the 13.1-mile distance. Runners can participate for charity, so the field includes runners other than club athletes chasing times. The event has reached at least its 18th edition, giving it a longer track record than many newer city half marathons.
