In the 100 m final the largely favored Usain Bolt was disqualified for a false start, enabling Yohan Blake to win the crown with a time of 9.92 s. In the 200 m Bolt won with a time of 19.40 s, which was the fastest time ever not to be a world record at that point. Blake and Bolt, along with countrymen Nesta Carter and Michael Frater, ran in the 4 x 100 metres relay, setting a new world record with a time of 37.04 s. In the 10,000 metres event, World Champion Kenenisa Bekele did not finish the race. The world record holder in 800 m, David Rudisha, won the event with his first gold medal at the World Championships. On the last day, Kenyan Abel Kirui became the third marathon winner to retain the title at the next World Championships, after Abel Anton and Jaouad Gharib.
