Event Overview

The Big Half is an inclusive running event in London that celebrates the diversity of the city and its local communities. First established in 2018, the event features a course that begins at the historic Tower Bridge and concludes at the Cutty Sark in Greenwich. The route travels through four London boroughs: Tower Hamlets, Southwark, Lewisham, and Greenwich.

The event offers several participation options to accommodate different interests and team structures:

  • Half Marathon: A 21.1 km race through the heart of the city.
  • New Balance Big Relay: A team-based relay event.
  • Big Mile: A shorter distance event focusing on community participation.

The Big Half is designed to be a vibrant celebration of movement, featuring local support and cultural elements throughout the course. The event includes specific provisions for participants with disabilities and offers community entries to encourage local involvement. Volunteers also play a significant role in the delivery of the event, assisting at locations such as water stations. Training resources and specific participant guides are provided for each of the distances to help runners prepare for the event day. Visit the organization's website for the most recent information.
