Bolt Completes a Double and Russian Women Break Through Loic Venance/Agence France-Presse - Getty Images In the last event in Moscow on Saturday, Jamaica's Usain Bolt, second from right, coasted to victory in the 200. He had already won the 100. MOSCOW - It was a big, upbeat night for Russia at the world track and field championships, and the good vibrations often came at the expense of its former archrival, the United States. In the span of five minutes Saturday, the Russian women broke the American grip on the 4x400-meter relay race and then got to celebrate the gold medal in the high jump after Svetlana Shkolina cleared 2.03 meters and Brigetta Barrett, the exuberant and uninhibited American, could not. The stands in Luzhniki Stadium - so often half-empty over the last week - were nearly full. The crowd was roaring, with the Russians actually drowning out the few thousand Ukrainians who have been carrying the cheering load during these championships. All this and Usain Bolt had not even run yet. But Bolt, when he finally did appear for the last event of the night, did not disappoint. He has been the sport's dominant sprinter and personality for five years, and he finished his latest individual sprint double at a global championships by winning the 200 meters in 19.66 seconds. The silver medal went to Bolt's Jamaican teammate Warren Weir in 19.79 and, in a mild surprise, the bronze to the American Curtis Mitchell in 20.04. The time was not among Bolt's most dazzling. His world record, set in 2009, remains 19.19. But Saturday's time would have been faster if he had not eased up in the final 10 meters. His last five strides before he reached the line were not at full speed, but then they did not need to be. Bolt said he knew he had the race won with 50 meters remaining. "I think after 150, you can kind of tell if you are going to win or not," Bolt said. I looked across and saw Warren was there, but I could tell he was tired, so I wasn't too stressed about that. And I checked my left, and there was no one there. So I would say probably about 150, I knew. Bolt, who will turn 27 next week, has now won every major sprint final in which he has been allowed to run since 2007. He swept the 100 and the 200 at the last two Olympics and has done the same at the 2009 world championships and these world championships. His only defeat in a global championships came in the 100 in 2011 in Daegu, South Korea, where he was disqualified from the final because of a false start. "I think I've done a lot over the years; my main goal was really to make myself a legend, and I satisfied that at the London Olympics last year," he said. But right now I'm just adding to my accolades, working hard, continuing to pile on the gold medals as much as I can and try to stay undefeated in the championships. He added: "My next big goal is to go to the Olympics in Rio and do something that has never been done before, and that's to win the 100 and 200 again. So we'll see what happens. Bolt should still have at least one more race to run with the 4-x-100 relay scheduled for Sunday, the final day of the championships. There were other intriguing subplots Saturday. With his country in the midst of turmoil, the Egyptian Ihab Abdelrahman el-Sayed took part in the men's javelin final and finished eighth in the competition, won by Vitezslav Vesely of the Czech Republic with a best throw of 87.17 meters. Stephen Kiprotich of Uganda followed his Olympic gold in last year's men's marathon with another gold in Moscow, winning in 2 hours 9 minutes 51 seconds. Meseret Defar gave the Ethiopian women a sweep of the track distance events, winning the 5,000 in 14:50.19 after her rival Tirunesh Dibaba had won the 10,000 earlier in the meet. Brianna Rollins of the United States, already the fastest women's hurdler in 21 years, proved that she could handle the pressure, as well. Rollins, a three-time N.C.A.A. champion in the 100 hurdles at Clemson, is now a world champion, too, after prevailing over a strong field in 12.44 seconds. Sally Pearson, the reigning Olympic and world champion, was second in 12.50, and Tiffany Porter, who once hurdled for the United States but now does so for Britain, was third in 12.55.
