From Tower Bridge to Buckingham Palace, a London half marathon is more than just 13.1 miles — it’s an unforgettable experience.

The city offers something for everyone, whether you’re chasing a personal best on a fast, closed-road course or taking in the atmosphere of charity-focused runs through London’s parks and riverside routes. With excellent transport links, world-class organisation and huge crowds lining the streets, it’s no wonder these events sell out fast.
