Usain Bolt edged ever nearer to the legendary status he craves after cruising into the 200m final with ease at London 2012.

While many would already consider the Jamaican superstar a legend for winning triple gold in Beijing and defending his 100m title on Sunday, Bolt himself insists he also has to retain his 200m title.

And the 25-year-old looked impressive tonight, effectively winning his semi-final before halfway and almost jogging down the home straight to win in 20.18.

Team-mate Yohan Blake was the fastest qualifier after also slowing down markedly in winning the opening semi-final in 20.01.
