Paris: Usain Bolt will be seeking to further hone his technique ahead of the world championships in South Korea later this month when he races the 200-metre at the Diamond League meeting here Friday.

It will be just the second time this season that the reigning world and Olympic double sprint champion, who is also world record holder in both the 100 and 200 metres, runs the longer distance.

"It's only my second 200-metre of the season [after winning in Oslo] and I'm just working on technique. It's all about execution in this race, and trying to get the perfect execution," said the 24-year-old Jamaican.

"I've got no time on my mind. If I get a good run off the corner and my technique is right it should be a good time. A fast time should come if I get it right," he said.

Making a comeback

Bolt will be up against training partner and fellow Jamaican Mario Forysthe and also Panama's Alonso Edwards, the reigning world silver medallist who is working his way back from injury but looked in good form in winning Tuesday's Reims International meet.

Edwards pipped Forsythe by one-hundredth of a second for victory in 20.28 seconds, with the time likely to go a lot faster today.

Cuban world record holder Dayron Robles was also an athlete to win in Reims, finishing in an impressive 13.16 seconds over the 110-metre hurdles against a 2-metre/second wind.

The Olympic champion said he had a clear goal going into the Paris meet at the Stade de France.

Women's sprinting

Jamaican women's sprint star Veronica Campbell-Brown will be looking to bounce back from a rare false start in Reims.

The double Olympic 200-metre champion and former world champion at 100 metres was disqualified for shooting out of her blocks too early in the 100 metres, which was won by Trinidadian Kelly-Ann Baptiste in 11.11 seconds.

"I have no idea what happened, I'm just disappointed," Campbell-Brown said.

"I'll try to figure out what went wrong and fix it for my next race."
