A new chapter is beginning for one of the world’s most iconic sporting events. From 2027, the London Marathon will expand into a two-day celebration of running, allowing up to 100,000 participants to take part across the weekend.
The historic move is designed to make the event more accessible while enhancing its impact on communities, charities, and the wider economy. Organisers estimate that the expansion could generate more than £150 million for charitable causes, further strengthening the marathon’s reputation as one of the largest fundraising events in the world.
Beyond fundraising, the increased participation is expected to bring significant economic benefits to London and the UK. Hotels, restaurants, attractions, and local businesses are likely to welcome thousands of additional visitors, creating a vibrant atmosphere throughout the city.
As runners from around the globe gather to take on the challenge, the expanded event will showcase London’s energy, diversity, and world-class sporting spirit on an even greater scale. The two-day format marks an exciting evolution for the marathon, ensuring that more people than ever can experience one of the most celebrated races in the world.
