London 2012: Usain Bolt Leads Jamaica To World Record In Men's 4x100m Relay

Usain Bolt increased his London 2012 haul to three gold medals, while helping his Jamaican teammates to a gold each in the men's 4x100m final on Saturday evening.

Not content with winning the 100m and 200m during the past week, Bolt, along with Nesta Carter, Michael Frater and Yohan 'The Beast' Blake, set a new world record in the event, clocking 36.84 seconds.

The United States got the silver, finishing in 37.04 seconds.There was controversy at the end of the race when the Canadian team, who finished third, were disqualified.

On hearing the result, the Canadians, who had been celebrating on the track with national flags, broke down in disbelief.

The disqualification was due to one of the team members treading on a lane line during the race, allowing the Trinidad & Tobago team to move up to bronze position with a time of 38.12 seconds.It wasn't a straightforward victory for the Jamaicans, with the American team building a lead over the first two legs. However, Blake, one of the stars of the London Olympiad, put in a blistering 100m run to leave Bolt level with Ryan Bailey at the change over.

The pair may have started level, but they didn't stay that way for long with Bolt, quickly got into his now familiar style, powering ahead to secure gold in the fastest time ever recorded.

As Bolt crossed the line, he pulled out the Mo-bot, the now familiar victory pose of Britain’s Mo Farah, who 30 minutes earlier had delighted the crowd with victory in the 5,000m.

It was a fitting end to the athletics programme at the stadium, with Bolt, undoubtedly the star attraction at the Games, stood atop the podium celebrating another win. As always, the Jamaican showman lapped up the applause from an 80-strong crowd all too aware that they had witnessed an athlete and a competitor unique in the history of track and field.

After the medals had been awarded, Bolt spoke warmly of the Olympic crowd - of the many Brits but also thousands of sports fans who had travelled to the capital to witness the fastest man on the planet.
