Volunteer kilties have taken to the streets of Glasgow handing out Tunnock's teacakes to passers-by to mark Random Acts of Kindness Day.

A total of 550 of the treats were handed out to Glaswegians in the space of an hour in a bid to encourage them to participate in Kiltwalk 2018.

Known as kilties, the network of tartan-clad volunteers oversee the organisation of events and cheer on walkers along the route to provide them with motivation.

On Friday, they were out in the city's Style Mile the day before Random Acts of Kindness Day on February 17, using the iconic snacks to entice people into taking part in or volunteering for Kiltwalk events.

The Kiltwalk, sponsored by Royal Bank of Scotland and backed by Sir Tom Hunter, attracted 14,000 walkers in 2017 and raised £2.5m for nearly 800 charities across Scotland.

Some of the money raised is distributed through the STV Children's Appeal, the official grant-making partner of the event.

Kiltwalk 2018 has already had a number of celebrity backers, with Rob Brydon, Gerard Butler and Andy Murray all issuing messages urging people to get involved.

Glasgow kicks off the walks on Sunday, April 29, with the The Mighty Stride which begins at Glasgow Green and ends 23 miles away in Balloch.

There are smaller events too, with the 14-mile Big Stroll and the six-mile Wee Wander.

This is followed by Aberdeen on June 3, St Andrews to Dundee on August 19 and Edinburgh on September 16.

All of these events also have three distances to choose from to suit walkers of different ages and abilities.

Paul Cooney, chief executive of the Royal Bank of Scotland Kiltwalk, said: "Thank you to Tunnock's for providing the teacakes and to our kilties.

"Our volunteers are a brilliant bunch for coming together to spread cheer in Glasgow to mark Random Acts of Kindness Day.

"We hope this small gesture helps to get people motivated to sign up to walk or volunteer at one of the four Kiltwalks taking place across Scotland this year.

"Whatever your age, whatever your ability we want to see as many people as possible take part this year as either a kiltie or a kiltwalker to make the events bigger and better than ever, raising even more money for charity."
