What's happened
The London Marathon will be staged over two days in 2027 to enable 100,000 runners to participate, doubling ballot chances and boosting charity income and the UK economy. The plan, backed by the mayor and multiple stakeholders, will preserve the traditional route from Greenwich to Westminster while highlighting a world-first city-wide celebration.
What's behind the headline?
Deep Dive
- The Double is pitched as a once-in-a-generation event to maximize participation and fundraising.
- It will split elite and mass participation across two days, with women’s events on one day and men’s on the other, while keeping the Greenwich-to-Westminster route.
- This shift tests the balance between mass participation and city disruption, with officials citing accessibility and economic impact as primary justifications.
- Forecast: the event will become a focal point for charity fundraising in 2027, potentially driving sustained public-health and tourism benefits if successful.
- Readers should watch for operational details in the coming months, including ballot timing and safety planning.
How we got here
Organisers have announced a one-off two-day edition for 2027 after a record ballot turnout for 2026. The move aims to widen access to participation, raise tens of millions for charity, and inject a reported £400m into the UK economy. The plan has required buy-in from city authorities, transport bodies and emergency services.
