ZURICH -- Usain Bolt and Yohan Blake have set Weltklasse meet records despite rain and cold wind at the Diamond League event on Thursday.
Bolt playfully shivered for the television cameras at the start of the 200 meters then timed 19.66 seconds in the fastest half-lap race seen in Zurich.
Earlier in the 100, Bolt's Jamaican teammate Blake blazed to a dominating victory in 9.76. Bolt did not run the 100. Tyson Gay of the United States was disqualified for a false start.
There was a major surprise in the 800 when Olympic champion David Rudisha lost to Mohammed Aman of Ethiopia. Rudisha was targeting the world record he set in London, but said he was unsettled by the poor weather.
