This is how the route is described at wikipedia
The course begins at three separate points around Blackheath at 115 ft above sea level, on the south of the River Thames, and heads east through Charlton. The three courses converge after three miles in Woolwich, where the Royal Artillery Barracks is passed.
As the runners reach the 6-mile mark, they pass by the Old Royal Naval College and head towards Cutty Sark drydocked in Greenwich. Heading next into Surrey Quays in the Docklands, and out towards Bermondsey, competitors race along Jamaica Road before reaching the half-way point as they cross the Tower Bridge. Running east again along The Highway through Wapping, competitors head up towards Limehouse and into Mudchute in the Isle of Dogs via Westferry Road, before heading into Canary Wharf.
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 St Paul’s Cathedral on Ludgate 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 385 yards, catching the sights of Big Ben and Buckingham Palace, and finishing in The Mall alongside St. James’s Palace
