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."
Olympic champion Usain Bolt and Yohan Blake will go head to head again on Sunday for the final of the 200m final at the Jamaican National Championships and Olympic trials.
On Friday, Bolt suffered a shock defeat in the 100m final when he was beaten by world champion Blake who clocked 9.75 seconds.
In yesterday's semi-final heats of the 200m, Blake crossed the line in a time of 19.93 to easily win his heat while won his in 20.26s.
The men's final is scheduled for 19.30 local time today (01.30 BST).
