Usain Bolt believes he can break his own world record after cruising into the 200 metres final with contemptuous ease at London 2012.

The 25-year-old looks an increasingly certain bet to retain his 200m title, effectively winning his semi-final last night before halfway and almost jogging down the home straight to win in 20.18 seconds.

Team-mate Yohan Blake was the fastest qualifier after also slowing down markedly in winning the opening semi-final in 20.01secs, but Bolt is certain he will put his training partner in his place once again today.

Bolt said: "No doubt whatsoever. I'm ready, this is my favourite event, so I'm looking forward to it."

Asked about breaking his record of 19.19s - set when winning the world title in Berlin in 2009 - Bolt added: "It is a possibility, definitely."
