The full route of the 2025 London Marathon will take runners on a tour through central London.

The race runs along both the north and south banks of the River Thames at various points throughout its 26.2mile route.

But running such a large event will require road closures at different points throughout the day as runners make their way through the capital.

Which roads will be closed for London Marathon 2025 and at what times?

There will be closures right across the route of the London Marathon occurring at separate times throughout the day.

In order to reduce the impact on traffic as much as possible,the M3 closure between junctions 3 and 4 which had been planned for that weekend has now been cancelled.

This means the closure between Friday,April 25 at 7pm until 6am on Monday,April 28 to install the Bagshot Heath Footbridge will no longer take place.

For more information on road closures,download the official guide from the TCS London Marathon website.

London Underground on marathon day

The London Underground,London Overground and Docklands Light Railway are running extra services throughout marathon day and are recommended as the best way to get around to keep up with the race action.

Due to the nature of the day,expect services to be busy with crowds of spectators along the route.

Stops near the marathon route are likely to be very busy,especially the Jubilee,Circle and District lines,and the DLR.

Cutty Sark station will be entry only,and there will be other amendments made to DLR services throughout the day.

On top of this,there is a reduced service on the Elizabeth line between Heathrow Terminal 4 and 5 and Paddington,and between Maidenhead and Paddington.

Transport for London is encouraging everyone to plan their journeys in advance and check the TfL website or TfL Go app for the latest travel information.

And remember,marathon runners wearing their bibs can travel on the Tube and London buses for free.

Buses on marathon day

Bus routes along the route of the marathon will either be diverted or will not run the length of their usual journey until the roads are back open.

If travelling by bus on the day,visit tfl.gov.uk/bus/status to see if your bus route is affected.

What time does the London Marathon start?

The race will kick off at around 8.50am when the Elite Wheelchairs class sets off.

Elite Women will follow at 9.05am,with Elite Men at 9.35am.

The mass event will then open for all other racers to set off between 9.35am and 11.30am.

Start times are allocated based on runners’ predicted finish time,which will have been given to organisers ahead of time.
