Overview
- Reports on Wednesday outlined talks to run the 2027 race over April 24–25 with about 50,000 runners each day and elite races on separate days.
- Organisers called the idea exploratory and unapproved, countering reports that described “advanced talks” or said it was close to confirmation.
- The Mayor of London’s office said it looks forward to working on feasibility, which is required before any formal sign-off.
- Interest has surged, with a record 1,133,813 ballot applications for the 2026 race after a 2025 edition that set 56,640 finishers and raised £87.3m.
- Supporters project about £130m for charities if the weekend expands, and two days would also extend road closures and add pressure on public transport.
