Thewomen's400 metres at the2015 World Championships in Athletics was held at theBeijing National Stadium on 24, 25 and 27 August.[1]Christine Ohuruogu of Great Britain entered the competition as the defending champion.[2][3]
Allyson Felix was known as a200 metres specialist, but two years earlier, her string of 200 meter championships was broken when she sustained a hamstring injury in the final. Based on winning the2014 Diamond League, Felix was qualified to enter the 200 metres at the World Championships but chose to forgo that opportunity to focus on the 400 metres. This was her bid to win the one title she didn't have under her belt; in the same event at the2011 World Championships, she narrowly lost toAmantle Montsho of Botswana. With world leaderFrancena McCorory unable to qualify at the American Championships, Felix was the favorite. Defending championChristine Ohuruogu, known for her late rush, also made the final.
With high expectations, Felix took off strongly running her first 200 metres. She kept building on her lead, coming off the final turn several steps ahead ofShericka Jackson the next out of the turn. While Felix didn't further advance her lead, she kept her margin on Jackson for a clear win.[4]Shaunae Miller made a powerful rush to the finish, passing Jackson for the silver and gaining on Felix down the home stretch. Jackson beat three other Jamaican teammates for the bronze.[5]
