The Jamaican sprint star Usain Bolt has repeated his Olympic sprint double at the World Athletics Championships in Berlin, blitzing to a staggering new world record of 19.19 seconds in the 200m.
The new mark bettered his own previous record of 19.30sec set in the 200m final of the Beijing Games last year.
The performance in front of a stunned capacity crowd at the Olympic Stadium caps an amazing few days for Bolt, who will turn 23 tomorrow and has the chance of adding a further gold to his medal haul in the 4 by 100m relay.
The Jamaican smashed his own 100m record when he ran 9.58sec to take gold in that event on Monday and showed again today that he has no rivals even close to challenging him when he is in his prime.
Panama's Alonso Edwards finished second in the 200 with American Wallace Spearmon third.
