Some essential road closures that may affect your location are required as part of The Vitality Big Half route, when up to 15,000 runners will pass through Tower Hamlets, Southwark, Lewisham and Greenwich.
To find out more about road closures that may affect you, please use the interactive map below or download our road closure information booklet.
Thank you for your co-operation and understanding in helping to make The Vitality Big Half a fantastic event.
Please note: since the leaflet was distributed by Royal Mail in January 2020, the reopening time of some of the vehicle crossing points has been extended. Please refer to the online leaflet for fully up to date information.
