The London Marathon is back with another star-studded event in 2025, set to take place on April 27 in the heart of the UK capital.
At one of the seven World Major Marathons of the year, more than 56,000 people are expected to run. This year, the event can break the world record for the most finishers in a marathon, surpassing last year's New York Marathon feat, which witnessed 55,646 cross the finish line.
Several elite athletes like Olympic gold medalist Sifan Hassan, runners-up Tigst Assefa and women's world record holder, Ruth Chepngetich, will grace the women's race line-up. Distance-running luminary Eliud Kipchoge will touch down in London for the first time since 2020.
Let's take a look at road closures, start times, and the weather forecast ahead of the 26.2-mile event.
The 2025 London Marathon Route
The marathon will tend to follow the route introduced in the 1981 edition. The runners will begin in Greenwich and next move to Woolwich, the Thames, and Bermondsey before running across London Bridge. A right turn will take them to Canary Wharf and the old Docklands before leading the way through Central London, Westminster Bridge, and concluding at The Mall in the vicinity of Buckingham Palace.
Some notable landmarks will be the Tower Bridge, the Tower of London, the London Eye, Big Ben, and the Cutty Sark, among others.
