Glasgow 2014: Laura Trott beats Elinor Barker to cycling gold

England cyclist Laura Trott beats Wales' Elinor Barker to the Commonwealth Games points race gold by the finest of margins at the Sir Chris Hoy Arena in Glasgow.

The pair finished level on points so the race was decided on which rider recorded the quickest final sprint lap, which was Trott by a bike length.

Scotland's Katie Archibald took bronze, making it an all-British podium.
