Usain Bolt glanced to his right once, twice, three times. No surprise: Nobody was there.

That’s how the quest began for his final individual sprint gold at the Olympics — a jog through the sunshine in the opening round of the 200 meters and a stress-free victory in the ninth heat of Tuesday’s qualifying.

He finished in 20.28 seconds, a time that means nothing. More importantly, he coasted into the finish line after triple-checking on Nigeria’s Ejowvokoghene Oduduru simply to make sure nothing crazy was happening.

“I know how to run the 200,” Bolt said. “It’s all about just reminding myself. Tomorrow, I’ll show up with much better progress. I have to run fast, and so I’m looking forward to that.”
