Double-Olympic champion Mo Farah is relishing the prospect of achieving an unprecedented 5,000 and 10,000m double at consecutive World Championships.
"No-one has done it and it would be amazing to make history," he said.
"To win both from Moscow to here would be incredible. It's not going to be easy but it can happen."

|Two Olympic: (5,000 & 10,000m at London 2012)|
|Three World Championship: (5,000m in 2011; 5,000 & 10,000m in 2013)|

Farah makes his first bid for gold on Saturday when he competes in the 10,000m final.
The 5,000m heats take place on Wednesday before the final on the penultimate day of competition on Saturday, 29 August.
Farah has endured a difficult year following allegations from a BBC investigation linking his coach Alberto Salazar with doping.
There is no suggestion that Farah had broken any rules and Salazar has denied the claims.
In June Farah spoke of his anger at how his name was "being dragged through the mud".
"It was hard but you just have to do what you do best and for me that is to run," he added. "You've got to be happy in training and in life to run well and I am. I'm in a good place."
Farah returned to the track with victory in the 5,000m at the Diamond League in Lausanne in July.
