The year 2025 is set to be a landmark one for sports and running enthusiasts across the UK. On 27 April, the annual London Marathon will once again bring together tens of thousands of participants and spectators from around the globe.

What to Expect from the 2025 TCS London Marathon

The London Marathon is far more than a sporting event - it’s a cultural phenomenon, uniting professional athletes, amateurs, charitable causes and countless supporters from the UK and beyond. For the 2025 edition of the marathon london route 2025, a record-breaking 840,000 applications have been submitted. Over 55,000 runners are expected to take part, cheered on by unprecedented crowds positioned along the 26.2-mile course.

Marathon London Route: Key Details

Since its inception in 1981, the London Marathon has traditionally started in Blackheath, on the edge of Greenwich Park. Runners set off in waves between 9:00 and 11:30 am.

From the start line, the course heads through Woolwich, past the Cutty Sark, through Bermondsey and across Tower Bridge where runners cross the Thames. The route loops around the Isle of Dogs before continuing through the City of London, eventually reaching the finish line at The Mall. In this way, the marathon london route 2025 covers many of London’s iconic landmarks.

The official finish line at The Mall is expected to close by 19:30. After that, the final arrivals will be welcomed at St James’ Park, where organisers will wait until midnight to greet the last participants.
