The Big Half London

The Big Half is a half marathon in London that follows a stunning 13.1-mile closed-road course, starting by Tower Bridge and finishing at Cutty Sark in Greenwich. The route goes through the four London boroughs of Tower Hamlets, Southwark, Lewisham and Greenwich.

London Marathon Events created The Big Half in 2018, in partnership with Sported, because we recognised that many of London’s running events didn’t truly reflect the communities they pass through. We want to change this by bringing Londoners of all backgrounds and abilities together in a celebration of the city’s diversity.

So while The Big Half features the some of the world’s best athletes – in the men’s, women’s and wheelchair elite fields – and thousands of mass participation runners taking on the same course, it’s much more than a half marathon. It’s a community running festival and everyone is invited!

The New Balance Big Relay is a great way to take on The Big Half as a team of family members, friends or work colleagues. It takes place on the same stunning central London course as The Big Half, from Tower Bridge to Cutty Sark, just split into four legs – so participants can soak up the fun and exciting atmosphere of the mass participation event without having to go the full distance!

The Big Mile is a FREE, fun, family-friendly mass participation event that takes place on the same finishing stretch as The Big Half, culminating at the iconic Cutty Sark. Because the route is only a mile long, it’s the perfect event for first-time runners or walkers, families with children of all ages and anyone looking to get more healthy and active – it’s also accessible to wheelchair users.
