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.[2][3]
After the championships, Kapachinskaya was disqualified for a doping violation for having stanozol and turinabol in tests held during the 2008 Olympics. She received a lifetime ban.[4] In 2017, McCorory was advanced to the bronze medal.[5]
