London Marathon Set for Historic Two-Day Format in 2027
Organisers of the London Marathon have unveiled detailed plans for a groundbreaking two-day event in 2027, which they describe as an "incredible celebration" with significant charitable and economic impacts. Advanced discussions are currently underway to make this one-off extension a reality, potentially allowing around 100,000 participants to take part—nearly double the usual number for the single-day race.
Economic and Charitable Benefits Projected
According to Hugh Brasher, the event director, the proposed two-day marathon could raise more than £130 million for good causes and bring in approximately £400 million in social and economic benefits to the country. These figures are based on research conducted at Sheffield Hallam University, highlighting the event's potential to boost local businesses, tourism, and community engagement.
Brasher emphasised that the idea has been met with overwhelming positivity, but organisers are cautious about maintaining the event's cherished status. "The London Marathon has been going for 45 years and it's got to a position of love, not only in the sporting calendar but the calendar of London," he said. "You can lose that love, and we have to be mindful of that. And that is why it is very much a one and done. But there is a need in this country to do it."
Event Structure and Consultations
The proposed format would dedicate one day to faster women, featuring the women's elite race, women's championship, good-for-age runners, and a mixed mass participation race. The other day would focus more on men's races while including a second mass participation race open to both men and women. This structure aims to enhance inclusivity and showcase athletic talent across genders.
Brasher confirmed that talks have been held with the BBC to ensure extensive coverage for both days, and further consultations are scheduled over the coming weeks. Key stakeholders involved in these discussions include:
- Police and emergency services
- Local boroughs and Transport for London (TfL)
- The Mayor of London and private landowners
"There has to be a huge amount of consultation, absolutely rightly," Brasher noted. "We do hope we will get signed off, but it is a huge undertaking, not only from our team's point of view, but also London's point of view."
Background and Future Implications
The Guardian initially reported on these advanced talks last month, sparking interest in how the event could evolve. While the 2027 extension is planned as a one-off to avoid diluting the marathon's appeal, it reflects a growing trend in major sporting events to expand formats for greater impact. If approved, this initiative could set a precedent for other marathons worldwide, balancing tradition with innovation to maximise benefits for charities and local economies.
