Jamaican sprint star Usain Bolt raced to redemption in 19.40 golden seconds to retain his world 200 metres title at the world championships in Korea, while Anna Chicherova ended Blanka Vlasic's four-year run as high jump world champion.
Bolt mouthed "believe" to the cameras as he celebrated his win. Nobody had stopped believing, even after he was disqualified from the 100 metres final last week, but certainly there was a sense that the natural order had been restored.
If anyone in athletics can match Bolt for sheer charisma, it is Vlasic but the Croatian, who was aiming for a third successive world title, found that counted for nothing against a rival in the form of her life.
Allyson Felix gathered her first gold medal of the 13th championships, after failing to win the 200-400 double, when the United States women won the 4x400m relay for the third time in a row.
Australia left it late to win a gold medal in Daegu, but finally succeeded through Sally Pearson's barnstorming run in the 100 metres hurdles. She finished in 12.28 seconds to set a championship record and become the fourth fastest woman ever.
