About The Big Half

The Big Half, London’s community half marathon, starts at Tower Bridge and finishes by the famous Cutty Sark in Greenwich. It was first held in March 2018 and has since continued to grow as a popular mass participation event, attracting charity runners through to elites.

The aim of The Big Half is to inspire runners of all backgrounds and experiences to enjoy the mental and physical health benefits of running, and to celebrate and represent London’s diverse population. A special £10 community entry route is available to encourage entries from under-represented community groups based in the local area.

The following events also take place in London on the same day as The Big Half:

The Big Mile

  • A free mass participation event held on the same finishing stretch as The Big Half. The route is only a mile long, making it the perfect event for first-time runners or walkers, families with children and anyone looking to get more active. It’s also accessible to wheelchair users.

The New Balance Big Relay

  • A team event that takes place on the same 13.1-mile course as The Big Half, with the route divided into four legs of around 5K each. It’s ideal for participants of mixed abilities or anyone who isn’t quite ready to complete the full half marathon distance alone.

The course

The 13.1-mile route of The Big Half and the New Balance Big Relay starts on The Highway by Tower Bridge and finishes beside the historic Cutty Sark in Greenwich.

The route passes through the four London boroughs of Tower Hamlets, Southwark, Lewisham and Greenwich – taking in Canary Wharf, Wapping, Tower Bridge, Rotherhithe and Deptford along the way – before finishing at the iconic sailing ship.

The Big Mile starts on Haddo Street in Greenwich town centre and heads out towards Deptford. It then doubles back through Greenwich to the Finish Line next to the Cutty Sark, which it shares with the half marathon.
