Rachel Cawthorn prepares for Olympics with knitting and Harry Potter

Leading British sprint canoeist Rachel Cawthorn has been described as a 'ball of fire' on the water - but she spends her free time immersed in knitting and Harry Potter books.

BBC South Today's Tony Husband met Rachel at the Eton Dorney lake, which will host sprint canoeing and rowing at London 2012, then travelled with her to the kayak club in Guildford where she first learned to paddle.
