The defending champion was Sanya Richards-Ross and despite her poor form earlier in the season, she ran 49.66 seconds in London just three weeks before the championships. The only faster athlete that year was Russian champion Anastasiya Kapachinskaya, who had run a personal best of 49.35 sec. Three-time 200 m world champion, Allyson Felix, was also challenging for the 400 m title, while Amantle Montsho (ranked third that year) had five straight wins on the Diamond League circuit. Jamaica's Rosemarie Whyte, Novlene Williams-Mills and Shericka Williams were also contenders, as was 2009 third placer Antonina Krivoshapka.Johnson, Len (2011-08-23). Women's 400m - PREVIEW. IAAF. Retrieved on 2011-08-23. The event started in controversy when reigning Olympic champion Christine Ohuruogu was disqualified in her preliminary race for a false start. 2011 was the first year of a new IAAF rule allowing no leniency for a false start. In the final, Montsho was a clear leader off of the turn, with Felix closing fast at the end to make the race close. This was Felix's personal best. Not only was this Montsho's personal best, but also the national record for Botswana. For the bronze medal, Anastasia Kapachinskaya was faster down the final 80 metres to pull away from Francena McCorory, who had run her personal best in the semi-finals.http://www.independent.ie/sport/other-sports/athletics-montsho-scoops-400m-title-2860822.html Montsho scoops 400m title 30 August 2011 Irish Independent 1 September 2011http://news.bbc.co.uk/sport2/hi/athletics/9574758.stm World Athletics 2011: Day two as it happened 28 August 2011 BBC Sport 1 September 2011 After the championships, Kapachinskaya was disqualified for a doping violation for having stanozol and turinabol in tests held during the 2008 Olympics.
