Transport for London (TfL) is urging runners, spectators, passengers and motorists to plan their journeys in advance of the London Marathon on April 26.

TfL has a dedicated travel information guide available at www.tfl.gov.uk/marathon to help people plan ahead of London’s largest annual running event.

Hundreds of thousands of spectators are expected to turn out to support over 35,000 people including world class athletes, celebrities and eager runners, raising millions of pounds for charities.

The route will take runners past some of the London’s most famous and historic landmarks. By planning ahead, spectators can choose the best place to watch – and a route map is available.

TfL Travel Ambassadors in their magenta uniforms will also be out on the day at Tube stations along the Virgin Money London Marathon route, providing travel information and assistance to customers. Real time travel information will also be provided through TfL’s website and social media channels throughout the day.

London's Transport Commissioner, Sir Peter Hendy CBE, said: “Each year Londoners show their support by lining the Capital's streets to cheer on the tens of thousands of runners taking part. With people coming from all over the world, raising money for causes close to their hearts, the encouragement they receive from spectators always makes a real difference. We've got TfL people who are taking part in the race and I wish them, and all the other participants, the very best of luck."

There will be a number of road closures in south east and central London on the day and 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 19:00.

Work to deliver the East-West Cycle Superhighway on the Victoria Embankment and Upper and Lower Thames Street will begin on 27 April and drivers are reminded to plan their journey in advance at www.tfl.gov.uk/eastwest.
