Jamaica relay team
Bolt claimed his third gold of the Championships.

Usain Bolt became the most successful athlete in World Championships history after leading Jamaica to gold in the 4x100m relay on the final day of competition in Moscow.

The 26 year old has now eclipsed both Carl Lewis and Allyson Felix in having collected his eighth world gold to add to two silvers. The American pair also have ten medals with eight golds with one silver and one bronze respectively.

Jamaica claimed victory with a world leading time of 37.36 seconds ahead of United States who won silver and Canada, who lodged a protest against a Great Britain baton change to take bronze.

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

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

Bolt's third gold of the championships firmly enhanced his status as the most dominant sprinter in athletics history and after equalling Michael Johnson and Lewis with eight world titles his success is showing no sign of letting up.

Despite crossing the line in third, the British quartet of Adam Gemili, James Ellington and Harry Aikines-Aryeetey and Dwain Chambers were disqualified after an illegal third baton change leading to Canada being given the bronze after an appeal.

"It is heart-breaking," Aikines-Aryeetey said. "We found out when we were walking to the medal presentation."

"I still got the baton in his hand, it felt right. I can't imagine how close it must have been. I am wondering if there has been a counter-protest.

"I don't understand, it just doesn't feel real. I gave him the baton, I ran for my life.

"We are in the industry where this is our bread and butter. This means a lot to us and we worked so hard for this."

However, Briton's women were the beneficiaries of a protest after their 4x100m relay as they claimed bronze as France were disqualified for an illegal baton change.

Hayley Jones had originally brought GB home in fourth as Jamaica, spearheaded by Shelly-Ann Fraser-Pryce, won gold ahead of United States and France, but the team of Dina Asher-Smith, Ashleigh Nelson, Annabelle Lewis and Jones collected the bronze.

Jones said: "I can't even think what to say, I'm shaking right now. We were all screaming in the corridor when we found out."
