Berlin: Jamaican Olympic champion Melaine Walker ran the second fastest women`s 400 metres hurdles of all time to win the world title in 52.42 seconds on Thursday.
Walker stormed down the home straight to overtake American Lashinda Demus, the 2005 world silver medallist who missed the 2007 worlds for the birth of her twin sons.
"I was not thinking, I was just running," the 26-year-old said of her closing 100 metres. "All I could do was focus on hurdling, one at a time, and I came out victorious."
"This is a fantastic time and a new championship record. Everything went perfect today."
She added that the entire Jamaican team had been inspired by the running of their team mate Usain Bolt. Bolt broke his world records in both the 100 and 200 metres at the championships and the country now has five golds.
"I am so proud to be Jamaican," Walker said.
Demus finished in 52.96 with Josanne Lucas of Trinidad & Tobago the bronze medallist in 53.20.
The world record in the event is 52.34 seconds by Russian Yulia Pechonkina.
