OSTRAVA, Czech Republic -- Usain Bolt started the European leg of his final season before retirement with a victory in the 100 meters at the Golden Spike meeting on Wednesday.
At the meet where he has most frequently competed in his career, with nine appearances, Bolt reeled in the rest of the field after a trademark slow start to cross the finish line in 10.06 seconds.
However, he had to hold off a strong challenge from Yunier Perez of Cuba, edging him by 0.03. Jak Ali Harvey of Turkey was third in 10.26.Bolt's performance fell short of his season best of 10.03, which was clocked at the 100 and 200 world record holder's final race in his native Jamaica on June 11.
"I'm not happy with the time," he said.
"It wasn't a good race, it was pretty slow."
Bolt mentioned a back problem that slowed him down.
"I'm going to see my doctor [in Germany] soon, I know he will fix every problem," he said. "All I need to do now is just to train hard and focus on getting myself into great shape. I'm not worried about that. It's just my back, it's always an issue. I didn't get injured, that's a key thing."
The eight-time Olympic champion is preparing for the World Championships in London in August, his final major competition.
The only other race he's scheduled before the worlds is the Diamond League event in Monaco on July 21. He's still undecided about other meets.
Mo Farah, meanwhile, claimed victory in the 10,000 meter event in what was likely one of his last races on the track.
The British distance specialist, who defended his Olympic titles in both the 5,000 and 10,000 at the Rio Games last year, plans to retire from track to move to road races after the worlds.
Farah held off a challenge from Kenyan Mathew Kimeli, surging past him with 200 meters to go to win in 27:12.09. Kimeli clocked 27:14.43.
"I honestly hoped I could run a bit faster time, however the wind slowed me down even though we ran quite a fast race from the beginning," Farah said.
