More than 30,000 people are to take to the streets of Glasgow for the Great Scottish Run.

Scotland's biggest mass participation running event this weekend started on Friday with thousands of schoolchildren taking part in a schools challenge over a 2k course.

"Super Saturday" will see children, families and "furry friends" take over Glasgow's George Square in a range of events including a 2.5k junior run, a family mile for children aged three to eight and a 100m mascot race.

On Sunday, the 10k will be set off by Bank of Scotland ambassadors Olympic gold medal-winning cyclists Callum Skinner and Katie Archibald while the half-marathon will be started by Commonwealth and Olympic medallists Charlie Flynn, Mark Bennett and Karen Bennett.

Starting in George Square in the heart of the city, the runners will follow iconic 10k and half-marathon routes through the city before concluding in Glasgow Green.

The event is set to be hotly contested, with Scottish Olympians Callum Hawkins and Tsegai Tewelde going head to head in a bid to become the first Scottish man to win the half-marathon since it was first staged in 1991.

Moses Kipsiro will be the man for the Britons to beat in Glasgow - the Ugandan Commonwealth 10,000m champion returns to Scotland to defend his Bank of Scotland Great Scottish Run title having taken victory in a time of 62.18 last year.

In the women's race, Kenyans Doris Changeiywo and Betsy Saina will battle for victory status.

Philip Grant, chair of the Scottish Executive Committee Lloyds Banking Group, said: "We can't wait for this year's Bank of Scotland Great Scottish Run to begin.

"It always promises to be a brilliant weekend for the whole family to enjoy and we're delighted to be involved once again.

"We would like to say a special thank you to those running for our charity of the year, BBC Children in Need. "It's time for all of your hard work and training to pay off, and we're looking forward to seeing you at the finish line."
