About us

The Big Half follows a stunning 13.1 mile closed-road course, starting by London's iconic Tower Bridge and finishing at Cutty Sark in Greenwich.

It's a vibrant and fun community running festival that brings Londoners of all backgrounds and abilities together in a celebration of the city's diversity - while raising much-needed funds for charity in the process!

Here's where you can shout about your Big Half challenge to friends and family and get those donations roling in.
