London Marathon 2027 – A Historic Two‑Day Edition Redefining the World’s Most Iconic Race

The London Marathon is one of the world’s most iconic running events, blending history, charity, and the vibrant spirit of the UK capital. In 2027, this legendary race enters a new chapter: for the first time in its history, the event will take place over two consecutive days, on Saturday 24 April and Sunday 25 April. This groundbreaking expansion—known as “The Double”—comes in response to unprecedented global demand and marks a transformative moment for mass‑participation sport.

Standing proudly among the Abbott World Marathon Majors alongside Boston, Tokyo, Berlin, Chicago, New York, and Sydney, London continues to set standards for inclusivity, atmosphere, and performance. The 2027 edition will welcome an extraordinary 100,000 runners, doubling its traditional capacity and making it the largest marathon weekend ever staged.

A Course Steeped in History, Now Shared Across Two Days

Both days will feature the classic London Marathon route: starting in Greenwich Park and Blackheath, sweeping over Tower Bridge, through the financial district of Canary Wharf, past the Tower of London and Big Ben, and finishing on the iconic stretch of The Mall, in front of Buckingham Palace.

To give every athlete category the spotlight it deserves, the elite fields will be split across the weekend:

• One day will host elite women, female para-athletes, and women’s championship & Good for Age runners.

• The other will feature elite men, male para-athletes, and men’s championship & Good for Age runners.

This structure ensures maximum visibility, broadcast reach, and crowd engagement for all competitors.

Record-Breaking Participation and Global Demand

Interest in the London Marathon has never been higher. The 2027 ballot attracted a staggering 1.33 million applications, the highest number ever recorded for any marathon worldwide. By expanding to two days, organizers are opening the door for more runners, more stories, and more unforgettable moments.

The World’s Largest Fundraising Event—Now Even Bigger

London is already the largest one-day fundraising event on the planet, generating over £90 million in 2026. With its new two-day format, the 2027 edition is expected to surpass £150 million in charitable impact, supporting thousands of organizations and causes across the UK and beyond. The economic ripple effect is equally impressive, with an estimated £400 million in total benefit for the country.

A Celebration of Community, Education, and Movement

The expanded weekend brings new opportunities for local engagement:

• Every London school will receive two guaranteed entries for teachers or staff.

• Boroughs along the route will receive additional places for community groups.

• Runners can combine the physical race with the virtual TCS London Marathon MyWay, creating a hybrid experience across the two days.

An Atmosphere Like No Other

With more than one million spectators traditionally lining the streets and millions more watching worldwide, London offers an atmosphere unmatched in global running. Whether you’re chasing a personal best, running for charity, or simply embracing the electric energy of the city, the 2027 London Marathon promises an unforgettable experience.

Two days. One iconic course. A historic celebration of endurance, community, and transformation.
