An 84-year-old army veteran is preparing to set off on a 22-mile hike for charity.

Major Andrew Wedderburn, former CO of The Black Watch, will take on the Cateran Yomp on Saturday along with his sons Dominic and Patrick.

Major Wedderburn, who has beaten prostate cancer and is also recovering from a heart operation, said he was told by doctors to get outside and take up walking, so he decided to sign up and raise funds to support former members of the armed forces.

The octogenarian is the oldest participant to take on the walking endurance challenge set in the foothills of the Cairngorms around much of Perthshire's historic Cateran Trail.

He said: "My sons tried to convince me to come along and act as support for the walkers' but I was determined to walk in the event myself so will be hiking 22 miles on the day and am very much looking forward to it."

The Yomp raises funds for ABF The Soldiers' Charity, who provide a lifetime of support to soldiers and veterans from the British Army and their families.

Major General (retired) Martin Rutledge, the charity's chief executive, said: "Every year hundreds of charity supporters lace up their walking boots and take on this challenge to raise money for us.

"The money raised by the Yomp has helped many thousands of soldiers, veterans or their families who have been in need of the charity's help.

"We are extremely grateful to Major Wedderburn, his sons and all of the 1000 plus walkers who are taking part in the 2018 Cateran Yomp."
