Christine Ijeoma Ohuruogu was born on 17 May 1984 in Forest Gate, Newham, London, and initially represented England at netball before turning her focus to athletics, reaching the 400m hurdles final at the 2000 Olympic Games while still a developing talent.
Ohuruogu broke through at senior level in 2006, winning Commonwealth Games gold in the 400m, and the following year claimed her first World Championship title in Osaka with a personal best of 49.61 seconds, also taking relay bronze.
At the 2008 Beijing Olympics, Ohuruogu produced a dramatic late surge to win 400m gold in 49.62 seconds, narrowly defeating pre-race favourite Sanya Richards-Ross by just 0.07 seconds, becoming Olympic champion in one of the tightest finishes in the event's history.
Ohuruogu added a second World Championship title in Moscow in 2013, breaking a 29-year-old British record, and took Olympic silver in London 2012 as team captain for Great Britain, cementing a run of nine consecutive global championship medals between 2005 and 2016 that she shares with Merlene Ottey and Usain Bolt.
Across her career Ohuruogu won Olympic, World and Commonwealth titles in the 400m along with six World Championship relay medals and two Olympic relay bronzes, retiring after the 2016 Rio Games as widely regarded as the most successful female British track athlete in history.
- Olympic 400m champion, Beijing 2008
- Two-time World Champion in the 400m, 2007 and 2013
- Commonwealth Games champion, 2006
- Olympic silver medallist and Team GB captain, London 2012
- Shares the record for medalling in nine consecutive global championships with Merlene Ottey and Usain Bolt
- A late surge can define an entire career. Ohuruogu's dramatic final-metres victory in the 2008 Olympic final, won by 0.07 seconds, became the defining image of her career.
- Sustained excellence across many years outweighs any single result. Her nine consecutive global championship medals reflect a decade of consistency matched by very few athletes in any sport.
