Christine Ohuruogu, English runner
Christine Ijeoma Ohuruogu, MBE (born 17 May 1984) is a British track and field athlete who specialises in the 400 metres, the event for which she is a former Olympic, World and Commonwealth champion.
The Olympic champion in 2008, and silver medalist in 2012, she is a double World Champion, having won the 400 m at the 2007 and 2013 World Championships. She has also won six World championship medals in the women's 4 x 400m relay as part of the Great Britain and Northern Ireland team and bronze Olympic medals with the women's 4 x 400m relay at the 2008 Beijing Games and the 2016 Rio Games, her final Olympics. Ohuruogu shares with Merlene Ottey and Usain Bolt the record for medalling in most successive global championships - 9 between the 2005 World Championships in Athletics and the 2016 Summer Olympics.
Ohuruogu's personal best time of 49.41 seconds, set at the 2013 World Championships, beat the UK record set by Kathy Cook in 1984 by 0.02 seconds, simultaneously making her the first British female to win two World Championship titles, and the first British female to win three global titles (both achievements retrospectively moved to Jessica Ennis following her promotion to gold in the 2011 World Championships). Her relay bronze at the 2016 Summer Olympics made her only the second British track and field athlete, after Steve Backley to win medals at three successive Olympic Games. She is coached by Lloyd Cowan.
