About the Big Half

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 2022 event will take place on Sunday 4 September.

Celebrating diversity

London Marathon Events created The Big Half in 2018 because they recognised that many of London’s running events didn’t truly reflect the communities they pass through.  We are happy to support bringing people of all backgrounds and abilities together in a celebration of the city’s diversity.
