Olympics: Bolt and Blake ease through 200m rounds

LONDON (AFP) - Usain Bolt eased through the first round of the Olympic 200m on Tuesday as the Jamaican took the next step towards a sprint double after having already retained his 100m title in style.

Reigning champion Bolt showed no signs of fatigue as he ran the bend hard before relaxing in the home straight and strode over the line to win in 20.39sec in the first heat on a chilly morning in the Olympic Stadium.

"This was an easy run. I am enjoying it," said Bolt. "This is my favourite event so I am looking forward to it."

His main challenger for the 200m, Yohan Blake, also negotiated his passage into the next round with ease, as the Jamaican who took the silver behind Bolt in the short sprint won his heat in 20.38sec.
