Marathon fever is set to hit London's streets with the Virgin London Marathon taking place on Sunday 25 April.
World-class athletes, celebrities and thousands of others are expected to take part in the 30th London Marathon raising millions of pounds for charities along the way.
With hundreds of thousands of supporters set to line the streets of London, TfL will be working to keep the Capital running.
With 20 London Underground (LU) and Docklands Light Railway (DLR) stations located along the route, the Tube and DLR remain the best way for spectators to get up close to see the action.
The DLR this year launched their new three car trains, increasing capacity on the Bank to Lewisham route, the DLR's busiest, by up to 50 per cent.
This means that, with longer DLR trains, even more people will be able to travel on the service to see and take part in the race.
Free travel will be provided to all runners and officials on the DLR and the Tube on race day until 5pm by showing an official Marathon tabard or race number.
Some road diversions and closures will need to be put in place for short periods while the race passes through.
A leaflet highlighting how to get to various stages of the course by public transport has been produced by TfL and is available online and from all LU stations.
Spectators can also get up to the minute travel information by contacting TfL travel information on 0843 222 1234.
The route and approach roads south of the Thames between Blackheath and Deptford will close, together with Victoria Embankment between Bridge Street and Northumberland Avenue, Westminster Bridge (both directions) and Bridge Street from 07:00.
Remaining roads from Deptford and north of the Thames including approach roads will close from 08:00.
A staggered road reopening programme will be in force throughout the day starting at approximately 11:00.
Roads are expected to be fully reopened by 19:00.
Buses travelling down roads affected by the London Marathon will either be diverted or will not run the full length of their route until later in the day.
