What's it all about? Bridges to Africa is a national sponsored walk event involving students from schools across London and the UK. Students join together to complete bridge walks in London, Manchester and Birmingham. The money raised by students is used to help build a new affordable secondary school in Uganda, through the charity PEAS.
