As the route leads away from Canary Wharf into Poplar, competitors run west down Poplar High Street back towards Limehouse and on through Commercial Road. They then move back onto The Highway, onto Lower and Upper Thames Streets. Heading into the final leg of the race, competitors pass The Tower of London on Tower Hill. In the penultimate mile along The Embankment, the London Eye comes into view, before the athletes turn right into Birdcage Walk to complete the final , catching the sights of Big Ben and Buckingham Palace, and finishing in The Mall alongside St. James's Palace. This final section of the route formed part of the 2012 Olympic Marathon Course.
