The Big Half 2020

Fundraising Target

Sign-up to turn your miles into smiles at The Big Half – London’s most exciting half marathon. Starting and finishing at Tower Bridge, join 11,000 other runners as your run through the streets of four London boroughs – Tower Hamlets, Southwark, Lewisham and Greenwich – whilst raising funds for children living with untreated clefts.

Charity Place:

Charity place registration has now closed and we are no longer accepting applications. If you have your own place in the race and would like to support Smile Train click here.

Own Place:

If you have secured your own place in The Big Half 2020 independently of the charity you can still join our team and support Smile Train. As you have your own place in the event you can raise as much as possible, with the funds you raise helping to give children access to a full range of cleft treatment services they would otherwise never receive and ultimately the opportunity for a better quality of life.


If you have any questions regarding the event or fundraising for Smile Train please contact us by emailing or calling 020 3805 7788.
