TCS London Marathon 2027 (The Double)

The TCS London Marathon 2027 takes place over two days, on Saturday 24 and Sunday 25 April 2027, in London, UK. The organiser calls it The Double: for the first and only time, the race is spread across two days so that 100,000 runners can take part. It is a major goal for running clubs, charity groups and active travellers worldwide.

About the London Marathon

The London Marathon is one of the world's major marathons, famous for its crowds, its charity fundraising and a route that passes landmarks such as Tower Bridge, Canary Wharf and the Houses of Parliament, finishing on The Mall near Buckingham Palace.

For 2027, the organiser's special two-day format means many more runners than usual. Charity places are a common way for international runners to take part, and the organiser's website lists charities and how to apply. Runners should check which day they are assigned when they receive their place.

For runners from the Gulf, North Africa and Asia, London is easy to reach with many direct flights, and the city's large international communities mean that many runners have friends and family cheering along the route. The race is also known for runners in fancy dress and huge charity fundraising efforts.

The London Marathon 2027 dates and venue

The London Marathon 2027 takes place on 24 and 25 April 2027, with races on both Saturday and Sunday. The organiser also runs a Meet our Experts event on 15 January 2027 to help runners prepare.

Entry options, charity places and race information are on the official TCS London Marathon website. Runners collect their numbers at the event expo before race day.

How to get to London for the London Marathon

London is served by Heathrow (LHR), Gatwick (LGW), Stansted (STN), Luton (LTN) and London City (LCY) airports, with direct flights from across the Middle East, North Africa, Asia and Europe. Heathrow and Gatwick have rail links to central London.

On race weekend, the start areas in south-east London are best reached by train or the Docklands Light Railway, as many roads are closed. Use the Underground and rail network to move around the city.

Where to stay

Greenwich and Blackheath are close to the start, while Westminster, the South Bank and the City are near the finish. Canary Wharf and areas along the Jubilee line offer good access to both.

With more runners than ever in 2027, hotels will be in high demand for marathon weekend, so book early once places are confirmed.

Runners often prefer a quiet room and an early breakfast on race morning, so confirm these details with the hotel. Staying near a rail, DLR or Jubilee line station makes the journey to the start and back after the finish much simpler.

Planning a group trip to the London Marathon

A group tour to the London Marathon 2027 can combine expo visits, the race on the assigned day, and sightseeing such as the Tower of London, the British Museum and a Thames cruise. Agencies working with charity runners should coordinate fundraising timelines with travel plans.

Advise runners on travel insurance and training. Check entry requirements for the United Kingdom with the official authorities, including any travel authorisation that may apply.

Supporters can follow runners at several points along the route using public transport and meet them in an agreed area after the finish. Because the 2027 race is split across two days, groups with runners on different days should plan their schedules and sightseeing accordingly.
