This is the only half marathon to take place on closed roads through Westminster and the City of London. Join #TeamBreakthroughT1D today!

The London Landmarks is fast becoming one of the most popular half marathon running events in the UK.

From cultural landmarks and heritage to the city’s quirky and hidden secrets, runners will get to explore the capital on a route like no other! 20,000 runners will take in fabulous views of London’s most iconic landmarks - including Big Ben, St Paul’s Cathedral, Nelson’s Column, the Gherkin, the Shard, the Tower of London and the London Eye - along the way.
