MOSCOW, August 8 (R-Sport) - Usain Bolt is yet to peak as a sprinter and is still capable of breaking his 100-meter and 200-meter world records, Jamaica's head athletics coach Michael Clarke said Thursday ahead of the world championships in Moscow.
Bolt has won three gold medals at each of the last two Olympics, but it has been four years since he last set a world record, prompting talk that the 26-year-old may have peaked.
"As for his peaking, he's still a young man and he appears to have a lot left in him," Clarke said. "I believe he'll do as well as he did in the past."
Clarke indicated that another world record was possible. "It's definitely very exciting," he said. "It would be good if he can have another world record, let's see what happens."
The athletic world championships will be held on August 10 to 18 at Moscow's Luzhniki arena, the track-and-field venue for the 1980 Olympics.
In the 100-meter in Moscow, Bolt will be without his three strongest rivals. Reigning world champion Yohan Blake is injured, while Tyson Gay and Asafa Powell have both failed doping tests. Taken together, they are the four fastest 100-meter runners in history.
But Bolt does not need his rivals to motivate himself, Clarke said.
"I think he is driven by his own inherent ambitions and with the athletes that he has around him," he said. "As to the absentees, I don't think that impacts him one way or the other.
