The 2025 TCS London Marathon has broken the world record for the most finishers in a marathon.
The number to beat was 55,646, set by the 2024 New York Marathon, and the official number of runners to complete this year’s London Marathon was 56,640 – almost 1,000 more than New York.
Hugh Brasher, chief executive of London Marathon Events, said: “The TCS London Marathon is the world’s greatest marathon, and it is now officially the world’s biggest marathon. It is difficult to put into words the emotions of today.”
It was a record-breaking day in London.
Tigst Assefa broke the women’s only world record. Sebastian Sawe ran the second-fastest London Marathon. And there was likely also a record for the number of fans lining the streets of London to support the runners.
There were a total of 41 world records broken at the London Marathon as well as the record for most finishers.
