BERLIN: Jamaican star Usain Bolt stayed on course to repeat his Beijing Olympic sprint double at the World Athletics Championships after producing an effortless run to coast into the 200m final here on Wednesday.

The 22-year-old Jamaican, who set a new world record of 9.58sec in winning the 100m on Sunday, and is also the 200m world record holder (19.58sec), seems to have run out of any real rivals and it is difficult to see him being beaten in final, injury or shocking mistake permitting.

The men’s 1500m final produced a storming race won in a last-gasp burst by Bahrain’s Kenyan-born Yusuf Saad Kamel, emulating his father Billy Konchellah who won two world 800m crowns for Kenya in 1987 and 1991.

Kamel clocked 3min 35.93sec, with Ethiopian world indoor champion Deresse Mekonnen claiming silver (3:36.01), and defending world champion Bernard Lagat, also Kenyan-born but now competing for the United States, at 0.19sec in bronze.

There was more joy

for Jamaican team on the track when Brigitte Hylton-Foster won gold and

Delloreen Ennis-London got bronze in the women’s 100m hurdles.

South African Caster Semenya won the women’s 800m in impressive style on the same day the IAAF, world athletics’ governing body, announced that she would undergo tests to have her gender verified.

The 18-year-old Semenya kicked with 300 metres to go and was uncatchable down the home stretch to clock a world lead of 1:55.45sec.

Defending world champion Janeth Jepkosgei of Kenya won silver at 2.48sec, with Briton Jennifer Meadows getting bronze.
