Olympic 200m: Usain Bolt vows good race

Usain Bolt strolled ever closer to Olympic immortality on Wednesday.

Jamaican superstar Bolt — chasing an unprecedented second successive 100m-200m double — booked his place in Thursday’s 200m final with an imperious semi-final victory, easing up after 100m to qualify easily in 20.18sec.

The 25-year-old, who lit up the Games on Sunday with a superb win in the 100m, warned that his 200m world record of 19.19sec could now be in jeopardy.

“It’s a possibility, definitely. I can’t say but the track is fast, it’s going to be a good race,” Bolt said. “There are going to be a lot of great competitors so I’m looking forward to it.”

Bolt is bidding to become the first man in history to successfully defend both his 100m and 200m titles.

His opponents in Thursday’s final will include compatriot Yohan Blake, who won his semi-final in 20.01sec, and like Bolt eased up well before the line.
