Poet and runner Helen Mort talks to retired Olympic track and field athlete Anyika Onuora about body image in sport. In the last of three programmes about body modification and the relationship between how we present ourselves physically to the world and how we feel, Helen swaps experiences with Anyika about striving for ’the perfect image‘ and the effects training and competitive sport have on the body’s shape. Anyika reveals her lack of confidence about her body and how she managed this whilst living her life in the public eye in front of vast crowds and TV cameras. Producer Sarah Blunt
