Latest News About London Marathon 2027

Here’s the latest on the London Marathon 2027 as of 2026:

• A two-day London Marathon for 2027 is being explored but has not been formally approved yet. Organisers have discussed a potential Saturday and Sunday format to accommodate more runners and greater spectator reach, with official sign-off still pending. It’s described as a one-off event if it proceeds. [source coverage indicates ongoing talks and no final approval yet][1][2][3]

• Reports suggest the plan could double participation to around 100,000 runners across the two days, potentially delivering substantial economic and social benefits for London if approved. However, scaling is contingent on coordination with partners and the London calendar, given other major events that weekend.[2][6]

• Media coverage notes that discussions involve prioritizing elite races on separate days (women on Saturday, men on Sunday) if the format goes ahead, but this remains contingent on formal consent from the relevant authorities and stakeholders.[3][1]

• Ballot and entry details for 2027 were starting to emerge in late spring 2026, but practical changes (including the two-day format) would come after formal approval and logistics planning. If approved, participation mechanics could differ from a traditional single-day ballot.[5][8]

Illustration: If London approves a two-day format, expect:

• Two competitive days with separate elite programs
• Expanded capacity and more corporate/sponsorship opportunities
• Complex logistics (road closures, transport, volunteers) requiring close coordination with the city
