The iconic London Marathon, scheduled for this Sunday, April 26, 2026, may be the last edition held as a single-day event. Organisers are in advanced talks to extend the race across two days from 2027, potentially doubling the number of participants.
Record Demand Drives Change
Since its inception in 1981, the marathon has traditionally been a one-day spectacle. However, surging popularity and unprecedented demand have prompted a rethink. A staggering 1,133,813 people applied through the public ballot for this year's race, a 36% increase compared to 2024. The 2025 event raised a record £87.3 million for charity and set a Guinness World Record for the most finishers in a single marathon, with 56,640 crossing the finish line.
Organisers Confirm Exploratory Talks
A London Marathon spokesperson stated: "The TCS London Marathon is the world's most popular marathon, and we are continually exploring innovative ways to enable more people to take part, while delivering positive benefits for London. Together with our partners and stakeholders, we are looking at the intention for the 2027 TCS London Marathon to take place across two days. No approval has been given at this stage. Our immediate focus is on delivering an incredible 2026 TCS London Marathon on Sunday 26 April."
The spokesperson added: "We are looking forward to amplifying one of the original aims of the London Marathon, which was 'to show happiness and sense of achievement in a somewhat troubled world'. Those words resonate even more now than they did almost 45 years ago."
Mayor's Office Supports Exploration
A Mayor of London spokesperson commented: "London is the sporting capital of the world and the Mayor looks forward to working with London Marathon partners to consider if it might be possible to host an event that will run across two days next year."
The proposed expansion aims to accommodate more runners while maintaining the event's iconic status and charitable impact. Further details are expected after the 2026 race.
