Great Britain's Mo Farah says he is ready for the "heavy" training needed to convert good form into successful defences of his 5,000m and 10,000m world titles in Beijing in August.

The 32-year-old, who set 2015's fastest 3,000m time in victory at the Anniversary Games, completed the same double at London 2012.

"There is still a little bit of work to be done," said Farah.

"The next couple of weeks will be heavy weeks and then I will ease down a bit."

Farah has continued working with coach Alberto Salazar despite doping allegations against the American, delivering strong results under scrutiny.

He finished just 0.12 seconds outside his own British 1,500m record in Monaco on 17 July, a week after an emotional 5,000m win in Lausanne.

Farah will spend the next month away from his family at his training base in the French Pyrenees before travelling to the British team's pre-championship camp in Fukuoka, Japan.

Despite beating the world's best at both 5,000m and 10,000m in the last two major championships, Farah says there is no room for complacency.

"I'm confident, but you never know," he said. "I should go out there and hopefully try and win the 10,000m for sure. And then the 5,000m is going to be a little bit tougher, to be honest with you.

Farah says he will be spurred on by the memory of the 2011 World Championships in Daegu when he came into the 10,000m final as the fastest man over the distance that year, but was run down by little-known Ethiopian Ibrahim Jeilan in the final 35m.

"The Kenyans and the Ethiopians are really strong - they always have someone coming through, so, in terms of the depth, it's really strong," Farah added.

"Anything can happen. Like four years ago, in 2011, it was Jeilan. I wanted to win the race. He came from nowhere.

"I need to keep doing what I'm doing, enjoying what I'm doing - keep smiling."
