Cumbria will next month welcome a pair of pioneers who are aiming to set a new record with a gruelling test of physical endurance.

Katherine Wilkins and Martin Johnston of The Retreat fitness and wellbeing centre near Riding Mill in Northumberland will be attempting the United Kingdom Four Peaks Row.

The challenge, which has never been done before, will see the pair attempt to row between Wales, England, Northern Ireland and Scotland, and conquer each country’s highest peak.

The pair are due to be landing their boat at Whitehaven on June 6, before setting off to climb Scafell Pike.

“This is something that’s not just about physical fitness. It is going to be mentally difficult as well,” said Katherine, 27, from Hexham. “There are a lot of elements that are out of our control.

“The sea can decide to be kind or it can be absolutely gruelling and we’re totally at the mercy of that."

Katherine, founder of The Retreat, will be attempting the challenge alongside head trainer, Martin, 30, from Haltwhistle, a former Royal Marine Commando.

“I’m excited and a little anxious because I don’t come from a rowing background, but I’m a bit of a yes man," he said.

“I can never turn down a challenge. Doing something that can nearly break you can make you a better person.”

On her own motivation, Katherine said it was “the thought of doing something that’s never been done and creating a new path of adventure for other people to enjoy.”

If completed, the challenge will see the duo climb 14,498 ft, by summiting Snowdon, Scafell Pike, Slieve Donard and Ben Nevis, and row 888 miles.

Katherine said they were preparing for the extreme mental and physical pressures their bodies could experience.

The expedition is being funded by corporate sponsors, but it will also be raising money for Mind. Visit their JustGiving page to donate.
