An adventurer who conquered one of the world’s toughest mountain challenges is set to star in a new TV series.

Former GB triathlete, Huw Jack Brassington, who lives in Cockermouth, fought off a ferocious storm as he took on the gruelling Paddy Buckley Round, otherwise known as the Welsh Classical Round.

The endurance challenge sees runners covering a distance of some 100km and climbing 8,000m which is the equivalent of scaling Everest, taking in no fewer than 47 summits – all in 24 hours.

And it will be featured as part of a new five-part documentary, 47 Copa: Her Huw Jack Brassington (47 Summits: Huw Jack Brassington’s Challenge), made by Caernarfon-based Cwmni Da to be screened on S4C, with the first programme on Wednesday, November 6 at 9.30pm.

During the most dangerous leg of the challenge, Huw battled 60mph winds and torrential rain as a huge storm hit the Glyderau mountain range in Snowdonia, pushing the boundaries of his strength and endurance further than ever before.

Filming became a dangerous and logistical nightmare for the crew, who described it as the Welsh equivalent to “Armageddon”.

“This challenge was pretty much at the edge of what I can do in good nice weather,” said Huw, 34, who hails originally from Caernarfon.

“Then the storm hit and I’ve never been in weather like it in my life. There were 60mph winds. It was the kind of weather that normally I wouldn’t think of stepping outside the door.

“We were literally running diagonally. I was running at a 45 degree angle to stay on my feet. The wind was coming and going in gusts and it was hard to keep going.

“I was running like a crab, my legs were in a half squat. At one stage, I looked down at my walking poles and realised I’d lost half of one as it’d smashed in half – my hands were so numb I just hadn’t realised.

“I fell three times. There was always a camera crew around every time. I was cursing them at the time but it is was all down to the well-timed preparation to get these camera guys in the right place at the right time.”

The route takes in the well-known high mountain ranges of Snowdon, the Glyderau and the Carneddau as well as the less visited ranges of Moel Siabod, the Moelwynion, Moel Hebog and the Nantlle Ridge.

The documentary follows Huw’s preparation for the challenge, including his meetings with famous athletes and sportspeople such as white water kayaker Geraint Rowlands, downhill mountain biker Emyr (Ems) Davies, para kayaker Llinos Owen and UFC fighter Brett Johns.

The series was produced and directed by Huw Erddyn, 34, who carefully plotted every stage of the endurance athlete’s journey.

A five-strong crew was recruited for filming during the day including four shooting directors and a drone pilot and another two shooting directors for the night shoot. As producer and director, Huw Erddyn was also a shooting director, poised at the support points throughout the challenge to capture the bulk of the story.

Mr Brassington, who lives with his wife Gwenllian, is a lecturer in engineering at the National College for Nuclear at Lillyhall, and is no stranger to endurance challenges.

A former Team GB Triathlete, he completed the gruelling BBC Ultimate Hell Week and was previously the focus of another documentary, as he took on the formidable Berghaus Dragon’s Back Race.

“He has a unique approach to training in that he doesn’t really like to train too much!” explained Mr Erddyn of the adventure star.

“He doesn’t like to run for the sake of running - instead he finds races to do. I have a huge amount of respect for him.”

Mr Brassington added: “A lot of people don’t tell their mates or family they’re doing these kinds of things. Well, think about being followed by five cameras and being filmed falling on your face in a pile of sheep poo. I didn’t even have time to put my hands down.

“I was losing my marbles by the end of it. There’s a lot of pressure in the build-up and it’s a bit of a melting pot and pressure cooker. The more work you put into something the more there is at stake. If I’d fallen at the first leg, then they’d be no film. It was a lot of pressure.”

However, the experience has not put him off completing a new challenge and he is considering cage fighting next.

“My plan is to rotate and wear out different parts of my body at different times and so I’m thinking of cage fighting next!” he said.

“Life is short and I’ve realised that early on. I don’t want to be sitting there aged 80 with any questions like ‘maybe I could’ve run five marathons on the bounce’? I want to be content – even if I’m in pieces. I think your body is there for using in every way possible.”
