Rio de Janeiro: Usain Bolt admitted he lacked sharpness after taking gold in a 100-metre race in Rio de Janeiro Sunday.
The six-time Olympic champion clocked 10.06 seconds to beat Britain's Mark Lewis Francis (10.42) and Jefferson Liberato of Brazil (10.44) on the Copacabana beach track, Xinhua reported.
"I had a poor start but I regained some of my poise later in the race," said Bolt, who was competing in his first individual 100-metre race of the year. "I felt a bit heavy. I need to compete in more races. I will be in better shape after that."
