Usain Bolt runs slowest 100 of career, isn’t worried about it (VIDEO)

The world's fastest man isn't concerned that he ran the slowest final of his career two months before the Olympics.

Usain Bolt still won the Golden Spike race in Ostrava, Czech Republic, but the 10.04 was the slowest time he's ever run in a 100-meter final. His previous high was 10.03. The last time he ran over 10 seconds in any race was 2009.

There was a slight headwind at the race and it was a chilly evening, two factors which didn't help Bolt recover from his usual slow start.

"It's hard to explain," Bolt said after the race. "I don't really know what went wrong."

A few days later, he was more reflective.

"I explained to my coach that my legs were not feeling that energetic, probably through a lack of sleep and not enough food," he told reporters while in Rome preparing for this week's Diamond League meet.  "Since I got here I've been trying to get a lot more sleep and eating better so everything is seeming to be on a better track. You never have a good race every time you run, you have to just put that behind you and move on."

He'll try to do that on Thursday. That race comes exactly four years after Bolt set his first world record at a meet in New York. He's a different athlete now, a long way from that brash young upstart trying to dethrone a national rival, but his goal will be the same in the Olympic tuneup: Prove he's going to be impossible to beat. This weekend gave opponents a glimmer of hope. Don't expect it to last long.
