Laura Muir broke the British indoor record over 5,000m at the Glasgow Miler Meet at the Emirates Arena.

Muir's time of 14 minutes 49.12 seconds beat fellow Scot Liz McColgan's 25-year-old record by 14 seconds.

"I am delighted to get it and it is nice to know now where I am at in terms of the 5,000m," said Muir, 23.

"I've been in South Africa training, and the sessions there since we came back were at PB times for 5,000m so I felt good going into tonight's race."
