London Marathon Expansion Shapes Transit Planning

London Marathon considers two-day format in 2027 after record 1.1 million ballot entries

London Marathon Eyes Two-Day Event for 2027

London Marathon organisers are exploring expanding the race to two days in 2027, officials said. The proposal aims to accommodate surging demand after the 2026 event received a world record 1,133,813 ballot entries. Nothing's been finalized yet, but the plan would enable more runners to participate in what's become the world's most popular marathon. The race currently causes major road closures and public transport disruption throughout London.

Record Demand Drives Expansion Plans

The 2026 ballot entries represented a 36 percent increase from 840,318 applicants in 2025, according to London Marathon Events. A record 56,640 people completed the 2025 race, raising £87.3 million for charity. The marathon, which first took place in 1981, is part of the World Marathon Majors group alongside races in Boston, New York, Chicago, Berlin and Tokyo. Officials said the expansion proposals are part of ongoing efforts to deliver positive benefits for London while accommodating more participants.

Route and Logistics Under Review

The race begins in Greenwich in south east London and ends on The Mall in St. James's Park in the capital's center, covering 26.2 miles through the city. Officials haven't specified how a two-day format would affect the route or whether both days would follow the same course. The event currently requires extensive coordination with transport authorities to manage road closures and service disruptions. London Marathon Events continues to explore innovative ways to accommodate the growing number of participants while minimizing impact on the city.

Mayor's Office Backs Proposal

The proposals have support from the mayor's office, with a spokesperson stating the Mayor looks forward to working with London Marathon and partners to consider hosting a two-day event. Officials haven't announced a timeline for when a final decision will be made. The 2026 London Marathon is scheduled to take place on April 26, and organizers said they'll release more details about the two-day format if the proposal moves forward.

Transit Disruption Expected to Continue

Runners and spectators should expect significant public transport changes during the marathon, whether it remains a single-day or expands to two days. Officials haven't said how a two-day event would affect the scope or duration of transit disruptions.
