Bolt, who missed out on defending his world 100-meter title after a false start saw him disqualified, rebounded to retain his 200-meter crown in an electric 19.40 seconds.
And come the relay, it could not have been better scripted for Bolt and his Jamaican sprint teammates of Nesta Carter, Michael Frater and Yohan Blake, who had gone on to win the 100m gold after Bolt was disqualified a week ago.
Carter went off like a rocket from the blocks, and smooth handovers to the dependable Frater and Blake saw Bolt in prime position for a home-stretch sprint.
Bolt again showed a determination going for the line that is said to often be missing.
Teeth clenched and eyes stuck on the trackside clock by the finish line, the 25-year-old dipped in desperation, his head pivoting to see if the record had been broken.
“For me it was just to go out there fast,” said Bolt. “We did just that. I am proud of my team; I'm happy with myself.
“I enjoyed being the anchor,” he said in reference to the fourth leg normally run by Asafa Powell, who missed these worlds with injury.
