Further coverage from Berlin as another four gold medals are decided. Usain Bolt and Tyson Gay are scheduled to go head-to-head in the final of the 200m. Bolt broke Michael Johnson's long-standing world record in Beijing and he might have to produce another scintillating display to depose current champion Gay.

On a busy night of track and field, Cuba's Olympic champion Dayron Robles goes for gold over 110m hurdles, while the women's high jump and 400m hurdles reach their conclusions. The men's decathlon is also nearing the finish line. Roman Sebrle of the Czech Republic is the defending world champion, though Olympic champion Brian Clay is absent from the championships due to injury.
