Big Half

The Big Half is a half marathon event in London that passes through four boroughs: Tower Hamlets, Southwark, Lewisham and Greenwich. The course starts at Tower Bridge and finishes by the Cutty Sark in Greenwich. The event was first held in 2018.

The programme includes multiple ways to take part, with different event formats on the same day:

  • Half marathon
  • New Balance Big Relay
  • Big Mile

The event information notes community involvement along the route and describes the race as inclusive, emphasising representation of local communities in the four boroughs. A limited number of charity places are available for those who wish to run for a charity.

Organisers publish participant guides, a spectator guide and training resources to support runners. Volunteer roles are part of event delivery and volunteers can apply to help at stations such as water points and route support. Safety, road closures and accessibility are covered in dedicated sections of the event information.

The description focuses on the course, event formats and community aspects of the Big Half without specifying entry procedures or race-day logistics. Visit the organization's website for the most recent information.
