The 26-year-old added 4x100m gold to his 100m and 200m triumphs and now has a total of eight golds and two silvers. 

 

Carl Lewis and Allyson Felix also have 10 medals but have eight golds, one silver and a bronze respectively. 

 

Jamaica won in 37.36 seconds with the United States second and Canada third after Great Britain were disqualified.

 

Britain finished third but lost their bronze after an appeal was lodged² against their second changeover. 

 

However, the women's relay team were later promoted to the bronze-medal position after France were disqualified for a similar infringement³. 

 

Bolt's latest triumph meant he joined Americans Michael Johnson, Felix and Lewis on a record-equalling eight world titles overall. 

 

The 100m and 200m world record holder⁴ also secured a sprint triple in World Championships for the second time, matching the trebles he completed at the 2008 and 2012 Olympics. 

 

"It is just great," Bolt said of the comparison. "I'll continue dominating. I'll continue to work hard. For me, my aim is to continue into the greatness thing." 

 

The United States team gave the Jamaicans a scare but Rakieem Salaam's handover to Justin Gatlin left the individual 100m runner-up off balance.

 

He clearly strayed into the Jamaicans' lane outside him but somehow escaped disqualification. 

 

It made no difference to Bolt, who streaked⁵ clear to complete victory in the sixth-fastest time ever. 

 

"I wasn't really worried about Justin. I knew if he got the baton⁶ in front of me, I could catch him," Bolt said. "So it was just going out there to run as fast as possible." 

 

Bolt delighted the crowd with a celebratory Cossack dance before parading round the track with team-mates Nesta Carter, Kemar Bailey-Cole and Nickel Ashmeade. 

 

Gatlin paid tribute to Bolt's success, saying: "To be able to rise to the occasion when an entire stadium full of people are either rooting for you or want to see you fail and you're able to hold it together, that takes talent.'' 

 

The British quartet also celebrated⁷ wildly after finishing third but James Ellington and Harry⁸ Aikines-Aryeetey failed to exchange the baton in time and the team were disqualified 30 minutes after the race. 

 

Jamaica also won the women's 4x100m relay to give  Shelly-Ann Fraser-Pryce  her third gold medal of the competition.
