The London Marathon is set to undergo a unique transformation in 2027, spanning two days to accommodate a larger number of participants and generate substantial financial benefits. This decision follows a surge in interest, with a record 1.33 million individuals applying for next year’s race. By hosting two separate events, the marathon aims to welcome 100,000 runners in 2027.
Scheduled for April 24 and April 25, the extended event is projected to raise over £150 million for charitable organizations and inject £400 million into the UK economy. All applicants for the upcoming race will automatically enter a lottery for both days, with the outcomes to be disclosed in early July.
Describing the move as a groundbreaking initiative, Hugh Brasher, the chief executive of London Marathon Events (LME), emphasized the event’s potential to redefine the marathon experience. By expanding participation to 100,000 runners across two days, the organizers anticipate significant contributions to charitable causes and a substantial economic impact on the UK.
Acknowledging the collaborative efforts involved, Brasher expressed gratitude to various stakeholders, including the Mayor of London, local councils, and emergency services, for their support in realizing this unprecedented event. Sadiq Khan, the Mayor of London, hailed the expansion of the London Marathon into a two-day spectacle in 2027, emphasizing the city’s status as a global sports hub.
The 2026 London Marathon witnessed a record-breaking 59,830 finishers and raised more than £90 million, solidifying its position as the world’s largest annual one-day fundraising event. Notably, the event marked a historic moment as Kenya’s Sabastian Sawe achieved a sub-two-hour marathon in a competitive setting.
In 2027, the marathon will feature elite women, elite female wheelchair athletes, championship runners, and ‘good for age’ female participants leading one day, while elite men, elite male wheelchair athletes, championship contenders, and ‘good for age’ male runners will take the spotlight on the other day.
Brasher revealed that the concept of a two-day marathon had been in development for nine years, originating in 2017. Although the initial aim was to implement it in 2020, regulatory approvals were not obtained at that time.
