Route information

The London Marathon course is one of the most iconic routes in running. Winding its way through the heart of the capital, with crowds lining the side of the route at every step, the course has barely changed since the race was first held in 1981.
The course begins starts in leafy Blackheath, heads east through Charlton and Woolwich for three miles, turns west and passes the Cutty Sark in Greenwich after six to seven miles.
It crosses the River Thames at Tower Bridge and then loops around London, right past the Shard. Continuing along past the 12th mile markers, runners will be taken past Canary Wharf and the London Eye.
Runners will finish in a blaze of glory along London's most iconic landmarks, Big Ben and The Houses of Parliament and Buckingham Palace.
