London Marathon plans big

Organisers are in advanced talks to stage the event across Saturday 24 and Sunday 25 April 2027, splitting the field into roughly 50,000 runners on each day to reach about 100,000 participants over the weekend. (marathonhandbook.com) The push follows a world‑record public ballot for the 2026 race, when 1,133,813 people applied for places, according to London Marathon Events. (londonmarathonevents.co.uk) The proposal, referred to internally as the “Double London Marathon,” would also allow the elite men's and women's races to be scheduled on separate days to spread elite fields and broadcast slots. (marathonhandbook.com) Organisers and partners say the expansion would increase capacity and charity income; the race set a fundraising record of £87.3m in 2025, a total organisers reported could grow with more amateur places.

(independent.co.uk) Officials have described the plans as exploratory and not yet finalised, and some reports say the two‑day layout is being discussed as a one‑off for 2027 with a return to the single‑day race thereafter if approved.
