When is the London Marathon 2025?

Sunday 27 April is the date of this year's London Marathon.

What time does the London Marathon start?

2025 timings are yet to be confirmed, but the mass participation race normally sets off from around 9.30am, with Elite and Wheelchair races setting off at staggered times from 8.30am.

What's the London Marathon route?

Greenwich and Blackheath is the starting point, with runners assigned one of three start lines. They all merge by the three-mile marker, following a route from Woolwich back towards Greenwich town centre (hello, Cutty Sark), through Rotherhithe and Bermondsey, and across Tower Bridge, at which point you're almost halfway there.

From here it's back east towards Limehouse, a big circuit around Canary Wharf and the Isle of Dogs, before doubling back through Shadwell to Tower Gateway. From here, the route stays close to the Thames all the way down to Westminster Bridge, where it turns onto Great George Street, continues onto Birdcage Walk, and sweeps round in front of Buckingham Palace for the iconic finish line on The Mall.

Running the route and need something to keep you going? Or watching on TV and need to orientate yourself? The London Marathon route passes several iconic landmarks, including:

  • Mile 6: Cutty Sark
  • Mile 12: Tower Bridge
  • Mile 18: Canary Wharf skyscraper
  • Mile 22: Tower of London
  • Mile 25: London Eye (on opposite Embankment)
  • Mile 25: Big Ben
  • Mile 26: Buckingham Palace

Where's the best place to watch the London Marathon 2025?

Depends what you're after. Some points along the route — Greenwich around the Cutty Sark, Tower Bridge, and of course, near the finish line around St James's and Westminster — get VERY busy, with people cheering on friends and strangers. If you want to soak up the atmosphere and are willing to put up with crowds, and standing for several hours, fill your boots.

Otherwise, head for somewhere where fewer crowds gather. From our experience, miles 9-12 around Rotherhithe and Bermondsey tend to be quieter, as do miles 14-21, east of Limehouse and around Canary Wharf.

There are five accessible viewing areas along the route for spectators with disabilities, at Cutty Sark, Canary Wharf, Limehouse, Tower Hill and Victoria Embankment — check the London Marathon website for exact locations.

Then of course, there's the easiest option...

How to watch the London Marathon on TV

The London Marathon will be shown live on the BBC as usual. The commentary usually begins around 8am on the day on BBC One, hopping over to BBC Two from around 2pm. We'll update when we have 2025 details.

Road closures for the London Marathon

The Marathon only takes place on one day, but it's such a big event that some road closures (and parking restrictions) usually start a day or two prior, and continue into the following Monday.

Obviously, any road on the route will be closed on the day, which means some bus services will be on diversion — check the TfL website for details. It's a rolling road closure situation, with the first parts of the course expected to start reopening by about 1pm, once the final runners have cleared the area, though the latter parts of the course aren't expected to reopen until late Sunday evening. If you live along the route, you're advised to move your car by the Saturday night, or risk being towed.

Full information about road closures is available on the London Marathon website.

How many people are taking part in the London Marathon this year?

Organisers haven't confirmed a total number of London Marathon participants for 2025 yet. In 2024, more than 53,000 runners took part, contributing to making it the world's biggest annual one-day fundraising event ever.

Any celebrities running the London Marathon this year?

If we're talking famous athletes, we know that all four reigning Olympic and Paralympic marathon champions (Sifan Hassan, Tamirat Tola, Catherine Debrunner and Marcel Hug) are taking part in the 2025 London Marathon.

Beyond that, it's likely many celebrities and well-known faces will take part again. Last year, the list included comedian Romesh Ranganathan, actor Ruth Wilson, Eastenders actors Emma Barton and Jamie Borthwick, who took part as their characters for a special episode of the soap, actor Christopher Eccleston and musician Tom Grennan.

Costumes and record attempts in the London Marathon

Other runners who made it special last year included:

  • Lloyd Martin, a Special Olympics Great Britain athlete who is aiming to become the youngest known person with Down Syndrome to complete the route;
  • Dave, AKA 'the Running Telephone' (pictured above), who is taking part in his 25th marathon in aid of Samaritans, dressed in a telephone costume;
  • Critical care paramedic Caroline Duncan, who's going for the record of 'fastest marathon dressed in a flight suit' to raise money for the North West Air Ambulance;
  • A group of people running in a joint 10-person bus costume, while individually dressed as ‘everyday heroes’ from doctors to zookeepers;
  • Wales Rugby League athlete Martin Turner, the first person to tackle the course in a rhino wheelchair costume. The costume — an adaptation of the usual costumes worn by runners supporting Save The Rhino charity — has been specially fitted to his wheelchair.

We'll bring you updates for 2025 when we have them.

You'll struggle to find a place to run at this late stage, though you might get lucky with a charity place. Contact charities individually for details.

How to enter the next London Marathon in 2026

Inspired by the top-notch running in this year's London Marathon, and fancy having a crack yourself? Ballots for places in the next marathon usually open soon after (or sometimes even the day before) this year's marathon, so keep your eyes on the London Marathon website.

If you're not successful, certain charities have places available each year. These are highly coveted, and you'll likely need to commit to a minimum fundraising amount.
