London Marathon course map poster

The London Marathon starts in Blackheath and runs to Woolwich, where runners from the three starts meet just before Mile 3. It loops around Cutty Sark in Greenwich, runs through Rotherhithe and along Jamaica Road in Bermondsey, and crosses Tower Bridge just before halfway.

North of the river it heads east along The Highway to Westferry, then circles through Mudchute, Docklands and Canary Wharf. The last five miles come back along The Highway, past Tower Hill and down Victoria Embankment to Parliament Square, Birdcage Walk and the finish on The Mall. Our print draws the line from the Red Start on Charlton Way.
