The London Marathon course is celebrated as one of the most iconic marathon routes in the world, offering runners a spectacular tour of the British capital while combining speed with unforgettable scenery. Starting in Greenwich and Blackheath, the largely flat route follows the River Thames and passes many of London’s most famous landmarks, including Cutty Sark, Tower Bridge, Canary Wharf, Big Ben, the Houses of Parliament, and Buckingham Palace before finishing on The Mall. The combination of historic architecture, enthusiastic crowds, world-class race organization, and fast road conditions has helped make London one of the premier destinations for both elite athletes chasing records and recreational runners pursuing their marathon dreams.
