And it works. After last week’s Fright Night with Derek Acorah, they somehow talked Borderers into jumping off the Penielheugh Monument, near Jedburgh. And they seemed to enjoy it.

This was the biggest, longest, scariest zip slide held in the region – at 150ft high and 1,000ft long. Safely installing the cables and ropes on the ancient edifice was a feat of mechanical brilliance. Ensuring everyone was able to jump on what was a pleasant, but incredibly windy day was just as impressive logistically.

But getting harnesses to fit snugly when 20 of the fund-raisers were wearing kilts was sheer genius.

Steve Mellor, ‘captain’ of the tartan-adorned squad named the Borders Barmy Army – which, as a group, raised more than £2,500 – was waiting to jump when the TheSouthern asked him what on earth made him want to do this.

“I saw the advert for it and thought ‘what the hell, let’s jump off a 150ft tower in high winds’. It looks rather frightening – and good fun,” he said.

Allan Johnston, regional manager for the Anthony Nolan Trust, was delighted.

He said: “It’s going really well, there is a fantastic bunch of people up here.

“A lot of money has been raised – I spoke to one person who has raised more than £1,400, which is absolutely amazing.

“The zip slide is looking quite spectacular. It’s very fast and everybody is coming back with a smile on their face, they had a great time.

“Looking at the pledges today, I think we are looking at a minimum of £15,000, which is fantastic. Added to the £18,000 from last week’s Fright Night with Derek Acorah, it’s not been a bad couple of weeks at all for the charity.

“Of course, all that money will be used to recruit many more donors on the bone marrow register and, hopefully, we will save a few lives.”

In fact, the total at the end of the day was an amazing £20,000, proving that when it comes to generosity, Borderers are hard to beat.

Anyone wishing to help raise funds for the Anthony Nolan Trust can enter any of its activities. For most of them, though, one will need more than an ounce of courage. They include a 10,000ft freefall parachute jump and swimming with sharks.
