Spectators and motorists are advised to check their routes before they travel, with road closures in place and many stations expected to be busier than usual.

From 7am there will be a number of road closures in south east and central London, from Greenwich Park to St James’s Park. Central and City closures will include all approaches to Upper Thames Street, Tower Hill and Victoria Embankment. Rotherhithe Tunnel, Tower, Southwark and Westminster Bridges will also be closed.

Motorists are advised to plan ahead and avoid driving near the affected areas, or travel at a different time if possible, and allow more time for their journey. There will be a phased reopening of the roads from around midday, with all roads expected to be fully reopened by 7pm.

London’s transport commissioner, Mike Brown, said: “The London Marathon is a sporting institution in the Capital which attracts thousands of runners and spectators every year. We have TfL employees who are taking part in the race, raising money for causes close to their hearts and I wish them, and all the other participants, the very best of luck.

“Public transport is the easiest way to get around on the day and I encourage anyone travelling around south east and central London to plan their journey in advance.”
