Latest News About London Marathon 2027

Here’s what’s happening with London Marathon 2027:

• There’s growing talk of a two-day London Marathon in 2027, potentially Saturday and Sunday, which could allow up to around 100,000 participants across the weekend. This idea has been reported by multiple outlets and reportedly has the backing of London’s mayoral office, though it had not yet received formal approval as of the latest briefings.[2][3][5]
• Ballot and entry details for 2027 were being released in 2026, with organizers signaling major changes tied to the two-day format if approved. This includes updated entry rules and the possibility of increased participation.[4][6]
• Several outlets emphasized the potential economic and social benefits of expanding to a two-day event, while noting that final confirmation depended on approvals from organizers and stakeholders.[7]

Illustration: If the two-day format goes ahead, participants could choose to run on either day, effectively doubling the number of slots and spreading crowd management across a weekend, which may impact logistics, charity fundraising, and spectator experience.
