The Kiltwalk raised £840,000 this year for Scotland's children's charities - and is set to benefit even more people in 2017.

Scottish entrepreneur and philanthropist Sir Tom Hunter was at an event in Glasgow's George Square on Friday alongside former Celtic player John Hartson to launch the 2017 Kiltwalk.

It has been announced that due to "significant demand" from non-children's charities, the Kiltwalk will be opened up to all good causes next year.

Sir Tom said: "In 2016 the true heroes of the day were the Kiltwalkers who raised an astonishing £840,000, with more to come, for 282 of Scotland's children's charities.

"Now my ask is obvious - be a hero again and sign up for next year and help us make Kiltwalk the biggest mass participation fundraising event in Scotland.

"The great news is next year all of Scotland's charities can use the Kiltwalk as a vehicle for their fundraising.

"It's simple; Kiltwalk enables Scotland's heroes deliver for the causes of their choice."

Among the good causes set to benefit next year is the John Hartson Foundation. The ex-footballer started the charity after his own battle with testicular cancer.

He said: "As soon as I heard that Kiltwalk was opening up to all charities, I jumped on a flight to be here to lend my support to the cause.

"This will encourage even more people to walk for the charity of their choice in 2017 and I aim to do at least one of the walks to raise awareness for 'Grab Life by the Balls'."

The Royal Bank of Scotland Kiltwalk will return to Glasgow on April 30, Aberdeen on June 4 and Edinburgh on September 17, with a new event held in Dundee on August 20.
