Getting to the top is hard enough but staying there is an even greater challenge. And so it could be argued that the 10th World Championship 400m victory by Tonique Williams Darling is even more remarkable than when she struck Olympic gold in 2004.

   Coming off the final turn the 27-year-old from the Bahamas held off the attack of both Sanya Richards (USA) and the former World champion Ana Guevara of Mexico displaying a hunger that permanent champions must have.

"I would say that being able to pull off the Olympic title and then come back a year later and pull off the World Championship title has just been a miler coaster (过山车) experience for me," she revealed. "It's really an historical moment for me and for the Bahamas, just to be able to do something like this. And so I feel really humbled and grateful and just overjoyed right now."

"It is not an easy experience. I will tell you, definitely, that in the off-season it was just a struggle to go out there every day and practice because coming off the top races and after the Olympics experience you are just kind of worn out mentally. It's not even physical. So you just go with the season, and work through it, and by the time, like two weeks away from this competition, I was hungry again and ready to be competitive."

Williams Darling credits a support group of friends and family, her husband, Bahamian 400m runner Denis Darling, with keeping her grounded when the natural tendency would be to celebrate and then rest on one's laurels (桂冠，荣誉), Most importantly she credits her Christian faith.

"My life has changed a little bit (since winning the Olympics) but as far as the competition and training it hasn't changed that much,' she declares. "One thing I have tried to do is to train like I have never won anything before. And I think that it was achieved because I could have been lackadaisical (无精打采的) and blown off the season or whatever. I just stayed in there and knew that everybody else was coming after me. That really helped me to stay motivated this season."
