The London Marathon is set to undergo a unique transformation in 2027, expanding over two days to accommodate a larger participation and generate significant economic benefits. Following a record-breaking 1.33 million applicants for the upcoming event, organizers decided to host two separate marathons, allowing 100,000 individuals to engage in the London Marathon in 2027.
Scheduled for Saturday, April 24, and Sunday, April 25, the extended event is anticipated to raise over £150 million for charitable causes and inject a £400 million boost into the UK economy, as stated by Hugh Brasher, the chief executive of London Marathon Events (LME).
All individuals who applied for the next year’s marathon will automatically enter a draw for both days, with the outcome to be disclosed in early July. Brasher expressed excitement about the unprecedented evolution of the 2027 London Marathon, calling it a one-time, transformative celebration of athleticism and community engagement.
By broadening the event to 100,000 participants across two days, the organizers aim to involve more people, charities, and communities in what is hailed as the world’s greatest marathon. The ambitious initiative is expected to generate substantial funds for charitable organizations and deliver a £400 million social and economic impact on the UK.
Acknowledging the pivotal role of various stakeholders, including the Mayor of London, local councils, and emergency services, Brasher emphasized the collaborative effort that enabled this groundbreaking event to take place in London and benefit the UK as a whole.
Sadiq Khan, the Mayor of London, praised the decision to expand the renowned London Marathon into a two-day affair in 2027, highlighting London’s status as a global sporting hub.
In 2026, the London Marathon witnessed a record 59,830 finishers and was recognized as the largest annual one-day fundraising event globally, raising over £90 million. The event also made history when Kenya’s Sabastian Sawe achieved the first sub-two-hour marathon time in a competitive race.
For the 2027 edition, the plan entails elite athletes and different categories leading the marathon on separate days, with a focus on promoting inclusivity and diversity in the sport.
Brasher revealed that the concept of a two-day marathon had been in development for nine years, originating in 2017, with the initial target set for 2020, which was postponed due to permit issues.
