Christine Ohuruogu looks back on winning 400m gold at the World Athletics Championships where she also broke the British record by two hundredths of a second.
Despite her achievement, the 2008 Olympic champion revealed she is always self-critical for motivation and believes her performance was not perfect.
Ohuruogu snatched victory from Botswana's Amantle Montsho on the line by a margin of just four thousandths of a second to break Kathy Cook's long-standing British record.
The 29-year-old is set to race in Friday's Diamond League finale in Brussels as well as the Great North CityGames on 14 September.
