The London Marathon is set to make history in 2027 by transforming into a two-day event, slated for the weekend of April 24–25. This expansion is unprecedented and allows for a record-breaking 100,000 runners to participate. The adjustment comes after an overwhelming response to the public ballot, with over 1.3 million entries. Despite this expansion, securing a spot in the marathon will remain highly competitive, with chances of selection still below 10%.
This enlarged format is expected to generate substantial charitable contributions, with over £150 million projected to be raised, marking it as the largest fundraising event in the history of UK sports. Additionally, the marathon is anticipated to contribute approximately £400 million in social and economic benefits. The inclusion of two days of events aims to accommodate the high demand while maximizing the positive impact on the community and charities.
The weekend’s schedule will be meticulously organized to cover a variety of races. One day will host the elite women’s race, the elite female para-athletes, the championship, and the “Good for Age” women’s categories, alongside a mass participation event featuring nearly 50,000 runners. The elite men’s race will headline the second day, which will also include another large-scale mass participation event, ensuring that both days offer exciting and inclusive opportunities for runners.
Participants will be limited to competing on just one of the two days, maintaining the spirit of fairness and competition. Those who entered the ballot can expect the results to be announced in early July, giving participants ample time to prepare. While the two-day format is confirmed as a unique celebration, the organizers have emphasized that the London Marathon will revert to its traditional single-day schedule in subsequent years, preserving its iconic status while adapting to current demands.
