Unbeatable Bolt - Jamaican sprinter elevates his game on biggest stages
All over the city of Berlin hang posters of Usain Bolt, his smile radiating, his hands held high in triumph as he crosses the finish line. Under the image is a simple phrase - 'Who faster?'

Jamaicans jump ahead again
First the sprints, now the hurdles. The Jamaicans are taking over that, too, from the Americans. Brigitte Foster-Hylton captured the 100-metre hurdles title in 12.51 seconds Wednesday, giving the island nation of 2.8 million its first gold in the event at the World Championships. Delloreen Ennis-London took bronze for Jamaica.

Jamaicans run, Russians walk
Just like the Jamaicans in the sprints, the Russians are perfect in the walking events at the World Championships. Russia made it three-for-three Friday when Sergey Kirdyapkin used a late surge to win the 50-kilometre walk, the longest event of the nine-day championships.
