A soldier with post-traumatic stress disorder is to scale one of Wales's tallest peaks – with a rowing machine strapped to his back.
Royal Fusilier Jonathan Roberson, based at Tidworth in Wiltshire, will climb up and down Pen y Fan – the highest mountain in the Brecon Beacons – on Saturday, as many times as possible in 24 hours.
He is taking on the world record attempt to raise money for the veterans' mental health charity that helped him through times of crisis.
Along with the 26kg rowing machine, the 28-year-old will also be carrying a 3kg medicine ball, and each time he reaches the summit he plans to row the height of the mountain before heading back down again.
He could achieve two Guinness World Records for his efforts – most repetitions of Pen y Fan in a full day and most hikes completed carrying a rowing machine.
"The minimum I have to do is six repetitions," he said.
"So that's up the mountain carrying the rowing machine, rowing the height of the mountain, and back down again. That's one repetition. But I plan to do 10.
"When it's done, I will have scaled over the height of Everest and rowed the height of Everest at the same time.

"Being in the military, Pen y Fan is like the gold standard. No matter what corps you've been in you've done the Fan and so that's why I chose it."
Mr Roberson's challenge is in aid of Combat Stress, a charity that supports current and former members of the UK Armed Forces with a range of community, outpatient and residential mental health services.
Originally from Newcastle, he joined the Army in 2013 and became a tracked armoured vehicle driver and gunner. In 2016, he qualified as an Army physical training instructor.
In 2017, he suffered a stroke during a strongman event, due to a hole in his heart, and spent 13 days in hospital learning how to walk and talk again.
He spent weeks in a rehabilitation unit and in 2020 had heart surgery to close the hole.
But his years of illness had a profound effect on his mental health and he began to struggle.
"For the past five years I've had a lot of medical issues and it resulted in me being diagnosed with PTSD," Mr Roberson said.

"When I first got diagnosed, I thought, 'I don't have that'. I had real stigma and I tried to do it myself, tried to grit it out, think to myself 'man up'. But that just did not work.
"I was mentally ill and it was making me even more physically ill too – I wouldn't eat, couldn't sleep and I was moody, stuff like that. So I reached out to the Combat Stress helpline."
He went on: "The first time I spoke to them I spent three or four hours on the phone. It felt good to talk to someone. And I just kept calling back and each time I felt better. There was absolutely no judgment.
"It has helped me massively which is why I wanted to raise money for them."
He said he is now able to focus on being a father to his five-year-old girl.
"Along with raising money for and awareness of the charity I'm hoping I can do more and help hopefully break the stigma of mental health," he said.
