Scot Katherine Grainger (top right) leads Great Britain's quest for their first ever gold medal in women's rowing.
She sits in the stroke seat of the quadruple scull, which has won three World Championship golds since taking Olympic silver in Athens in 2004.
Frances Houghton, Debbie Flood and Annie Vernon are behind Grainger in a crew that sees its main rival as China, who won their only races against GB this year.
Off the water, Grainger has a black belt in karate, Houghton is a part-time Spanish tutor and Flood is a trainee prison officer. Vernon, whose parents farm cattle in Cornwall, is in charge of making "lucky pasties" for race days.
The women's quads are in action first at 0930 BST on 10 August, with the heat winners qualifying directly to the final the following Sunday, also at 0930.
