MOSCOW ־ At the end of Day 1, Usain Bolt is on track to recapture the 100-meter gold he lost at the last world championships and Mo Farah already has the 10,000 title he missed out on two years ago.
Even if a false start in his heat was reminiscent of what disqualified him in the 2011 final, it was the runner next to him that was sent packing, not Bolt.
On the second attempt, the Jamaican set off confidently and cruised all the way to a time of 10.07 seconds for the 7th fastest time of the day.
"I wasn't really worried," Bolt said of the false start. "I was a listening for the gun, so that was good."
It did not phase him one bit. After all, the stadium had been filled with the reggae sounds of Bob Marley's classic "Three Little Birds," with the lyrics "Don't worry, 'bout a thing. 'Cause every little thing is gonna be all right."
Two Americans had the top times with Mike Rodgers clocking 9.98 and 2004 Olympic champion Justin Gatlin also dipping under 10, with 9.99.
Looking around him though, Bolt will know he is the overwhelming favorite in the absence of injured defending champion Yohan Blake and American star Tyson Gay, who is out because of a doping scandal.
"I am in great shape," Bolt said.
Bolt will be looking to add the 200 and the 4x100 relay title to make it a golden triple one year after a similar feat at the London Olympics.
Out on the track, his "Lightning Bolt" pose was only matched by Farah's "Mobot," holding his hands over his head in a heart shape.
In a tantalizing finish to the 10,000, the double Olympic long-distance champion from Britain had to fight off defending champion Ibrahim Jeilan over the last 150 meters. But instead of giving in at the line like he did two years ago, Farah's finishing speed was such that he had time to cover his face with his hands and cross the line with his arms wide open.
"I won the medal that was missing," Farah said.
Farah now has to defend his 5,000 title next Friday and, at 30, establish himself as the defining long-distance racer of his time with another 5,000-10,000 double in as many years.
