Usain Bolt created yet another piece of athletics history tonight with a sensational victory in the 200 metres at the World Championships in Berlin.
After winning the 100m with a new world record of 9.58 seconds on Sunday, Bolt completed the sprint double by smashing his own world record in the 200m for good measure.
Bolt stormed to victory in the Olympic Stadium in 19.19 seconds, slashing 0.11secs off the time set in Beijing last year, with Panama's Alonso Edward claiming silver in 19.81s and American Wallace Spearmon the bronze in 19.85s.
Bolt, who celebrates his 23rd birthday tomorrow, becomes the first man to hold the 100 and 200m world and Olympic titles at the same time following his triumph in last year's Olympics.
The Jamaican superstar again looked supremely relaxed before the race, wearing a t-shirt bearing the phrase ‘Ich Bin Ein Berlino’ in reference to Berlino the bear, the official mascot of the championships.
A false start heighted the tension in the stadium, but Bolt was in a determined mood once the race got under way at the second attempt, powering round the bend and gritting his teeth in determination until crossing the line and seeing the time on the electronic display.
‘I can definitely say I didn't expect that because I was a little bit tired,’ Bolt told the BBC. ‘I said let's try because people are really looking out for this, I said it won't hurt to try. So I tried really hard and now I'm really tired.
‘Maybe next time I should just run the 200m or the 100m alone. My form was going backwards. I wasn't running upright. It wasn't a good race but it was a fast one.’
Ariane Friedrich was unable to deliver Germany's third gold medal in the women's high jump, Croatia's Blanka Vlasic retaining her title with a clearance of 2.04m.
Russia's Anna Chicherova and Friedrich both cleared 2.02m, with Chicherova taking silver on countback.
A blanket finish in the men's 110m hurdles saw the medallists separated by just 0.01s.
Ryan Brathwaite of Barbados took gold in 13.14s with American duo Terrence Trammell and David Payne claiming silver and bronze respectively in the same time of 13.15s.
Jamaica's Melaine Walker added the world title to her Olympic crown in the 400m hurdles, the 26-year-old clocking the second fastest time in history of 52.42s.
American Lashinda Demus took silver in 52.96s with Josanne Lucas of Trinidad third in 53.20, a new national record.
Walker was given a piggy-back by the championship mascot Berlino on her lap of honour, but was sent sprawling to the track when the bear crashed into the back of a cart carrying the hurdles.
