The Big Half is one of the United Kingdom’s most popular and inclusive half marathons, bringing together elite athletes, club runners, first-time participants, charities, and local communities for a celebration of running in the heart of London. Created by London Marathon Events, the race was designed to showcase the diversity of the British capital while making the half marathon distance accessible to runners of all backgrounds and abilities.
The 21.1-kilometre course follows a spectacular point-to-point route through some of London’s most historic and culturally significant neighbourhoods. Beginning near Tower Bridge and finishing at the iconic Cutty Sark in Greenwich, runners experience a journey through East and South London that highlights the city’s multicultural character, vibrant communities, and world-famous landmarks. The route passes through boroughs including Tower Hamlets, Southwark, Lewisham, and Greenwich, attracting enthusiastic local support throughout race day.
Unlike many large-city races that focus primarily on elite competition, The Big Half places a strong emphasis on community participation and inclusivity. The event weekend includes family activities, shorter races, entertainment, charity fundraising opportunities, and community engagement initiatives. This approach has helped establish The Big Half as one of the UK’s most welcoming mass-participation running events.
The race attracts a deep field of competitive athletes while remaining highly accessible for recreational runners seeking their first half marathon. The relatively flat profile, excellent organization, closed-road course, and enthusiastic crowds make it a popular target race for runners chasing personal bests. Participants also benefit from the expertise of London Marathon Events, the organization behind the world-renowned London Marathon.
For international runners, The Big Half offers a unique opportunity to experience a professionally organized major-city race without the challenges of securing a London Marathon entry. Combining iconic landmarks, diverse neighbourhoods, community spirit, and world-class event management, The Big Half has become one of Europe’s premier standalone half marathon events.
