In the Olympic Park and across the capital there are seventy thousand Games Makers working a total of eight million hours helping sports fans get from A to B, and they're doing it all for free.
They volunteer at every Olympic venue and without them London 2012 wouldn't be able to operate.
Graham Satchell went to meet some of these hard working volunteers.
