Christine Ohuruogu 'heartbroken' to lose 400m title
Great Britain's Christine Ohuruogu said losing her 400m Olympic title is "heartbreaking", after being forced to settle for silver at London 2012.
American Sanya Richards-Ross claimed gold in a time of 49.55secs, while compatriot DeeDee Trotter took bronze.
Ohuruogu's time of 49.70 seconds proved not fast enough to enable her to successfully defend the title she won at the Beijing Olympics in 2008.
