WORLD Champion Yohan Blake says he is still working on improving the execution of the first part of his 100m race, as he prepares for the Jamaican Trials and the Olympic Games later this year.

Daegu, South Korea, Blake, who at 21 years old was the youngest ever 100m World Champion, says he still has some work to do on his start and the first 30m of his race.

In a teleconference on Tuesday to promote the Adidas Grand Prix in New York in June, Blake said while he is not doing anything different in training from last season, he was working on his start “and the technical aspects of his race, especially the first 30m”.

He also said that if he was to improve his start and curve running he would run faster than the 19.26 seconds he set last year in a late season European meeting, the second fastest time ever for the 200m, only behind Bolt’s world record.

Blake ran his personal best 9.82 seconds in the 100m twice last year but refused to be drawn into how much faster he can run.

He said training with Bolt had forced him to work harder every day and even when he was supposed to be resting.

He said coach Glen Mills gave him the nickname ‘the Beast’ as he had to rein him in several times when he was training during a rest period.

“Every time Usain takes two steps (in training) I have to take four to keep up,” he said, before adding that any edge he has over the double world record holder was that he worked harder on the training track.

Bolt, he said, “will not false start again in London”, so he had to make sure his start and the first part of his race was up to standard for the big clash.

Before they get to London, however, Blake said the first hurdle would come in June at the Jamaican National Trials and admitted that being nervous at the starting line was “part of being human”.

With so many world-class sprinters vying for the three spots to London, Blake, who won a World Junior Championships relay gold medal in Beijing in 2006, says the Trials will be competitive.

He listed Bolt, former world record holder Asafa Powell, two-time World Junior Champion Dexter Lee, as well as Commonwealth Games champion Lerone Clarke as some of the names that could make an impact in the 100m final at Trials.
