This year's London Marathon is set to break the world record for the biggest annual one-day fundraising event, according to organisers.

The 2025 event has already raised more than £75m for charities, beating the existing world record of £73.5m, set at the 2024 TCS London Marathon.

Enthuse, the official online fundraising partner of the marathon, announced £34m had been raised so far on its platform, while £41m has been donated via JustGiving – with the final total to be announced in September.

This year's marathon also broke a Guinness World Record (GWR) for the largest number of finishers.

A total of 56,640 participants crossed the finish line, beating the 55,646 set by the TCS New York City Marathon in November 2024.

Additionally, 41 other GWR titles were achieved from 87 attempts, including one involving a participant dressed as a traffic cone.

Chester Mojay-Sinclare, from Enthuse, said: "We're incredibly proud to kick off the first year of our new 10-year partnership as the official fundraising partner of the TCS London Marathon.

"The enthusiasm for taking part in the marathon has never been stronger, and we're excited about the impact we can make over the next decade."

Hugh Brasher, from London Marathon Events, organisers of the TCS London Marathon, said: "That is a wonderful achievement and huge thanks to every single person who fundraised and to all those who donated to a huge array of charitable causes."

The ballot for the 2026 TCS London Marathon, taking place on Sunday 26 April, is now open and will close at 16:00 BST on Friday 2 May.
