London’s 46th Marathon will draw more than 59,000 finishers, a new high after 56,640 slipped through in 2025. Organisers hint a 2027 two‑day format could push the tally to 100,000 and lift charity funds past £130 m. The race starts in Greenwich Park, where Sir Mo Farah and Ellie Kildunne will launch the event live on BBC.

Elite fields feature all four title‑holders: Sabastian Sawe, Tigst Assefa, Marcel Hug and Catherine Debrunner. Assefa, the Olympic silver medallist, eyes a new women‑only world record, while Hug vies to equal Britain’s David Weir with an eighth win. Prize money tops $55,000 (£40,500) per winner, with bonuses reaching $150,000 (£111,000) for the elite men and women.

Britons Mahamed Mahamed, Phil Sesemann, Patrick Dever, Rose Harvey, Eilish McColgan, Jess Warner‑Judd, David Weir and Eden Rainbow‑Cooper round out the home squad, hoping to spark crowd support. With the women's race starting 30 minutes before the men, the event remains a pure women‑only contest. Organisers aim to cement London’s status as the world’s most popular biggest marathon.
