A charity daredevil has scaled the three highest mountains in the UK in a 59kg deep diving suit. 

The challenge, also known as the 'Three Peaks Challenge', involves climbing to the summits of Ben Nevis in Scotland, Scafell Pike in England and Snowdon in Wales.

The difficult challenge is usually carried out in normal clothes over 24 hours, but longtime UK charity fundraiser Lloyd Scott wanted to go that one step further, all in aid of charity.

"I decided to put my own kind of unusual brand of fundraising to it and decided to attempt this particular challenge wearing my deep sea diving suit." Scott told CGTN Europe.

The challenge took Scott eight days to complete and wasn't without its difficulties.

"It was just stones, rocks, pebbles, gravel. More rocks. Bigger rocks. And through the grill I could see about three yards in front of me. So I would look at what was actually three yards in front of me. So at times it was almost like a bit of a, if not a leap of faith, a step of faith.

On this occasion, he decided to raise money for the Lords Taverners, a charity dedicated to allowing opportunities for young people to take part in sport across the UK. 

How a day in 1987 changed his life

A former firefighter, Scott's life changed forever after saving two children from a blaze in 1987. 

Shortly after, he began to experience breathing difficulties with tests revealing he had Leukaemia that required complicated bone marrow surgery. 

"I was very fortunate. I mean, at the time my chances of finding a donor and coming through the transplant were less than 10 percent. So I'm very lucky that I actually managed to come through that particular procedure." He said.

A charity champion

After successful surgery, Scott decided to give something back to those who had effectively saved his life by taking part in a number of challenges.

He has now completed dozens of events, raising millions for cancer and children's charities in the process.

Challenges included the completion of multiple London Marathons dressed up in costumes such as Indiana Jones with a large boulder attached to him, a yellow submarine and he even crawled around the course in a snail costume. 

In 2004 he cycled across Australia using an old-fashioned penny farthing and then in 2005 Scott swam from the most northern point in the UK to the most southern point in a swimming pool that was attached to a lorry that drove the 970km distance. 

He also holds the world record for longest recorded time to complete a marathon when he completed the London Marathon in five days, eight hours, 29 minutes and 46 seconds in - yes, you guessed it -  his deep-diving suit. 

"I did expeditions to the South Pole, the North Pole... I did an ultramarathon through Death Valley, so I kind of had a fairly extreme way of thinking." Scott said. 

How COVID-19 affected the challenge

The Three Peaks Challenge wasn't Scott's first choice of challenge for 2020. 

"We kind of planned to do something down the Nile and use the current to help sort of push me down. Obviously, once the COVID-19 pandemic affected everybody around the world, that was just going to be impossible.

"So we kind of had to come up with an alternative. And I had thought about doing the three peaks for some time. So it's something that obviously was a little bit more contained, something that we could actually go out and do and not break any regulations as they stood at the time." He said. 

What's next for Scott?

Now 59 years-old, he said if he was to attempt another challenge, it would have have to eclipse the Three Peaks Challenge, both in terms of difficulty and money raised, but admitted that would "very, very difficult."

However he didn't rule out the idea completely, leaving the door open to potential charities who want to raise money alongside him.

"There is a little kind of opportunity, gap or you might say terms and conditions that if somebody approached me and said, look, you know, if with your involvement, we could do this project and it would raise a serious amount of money for cancer sufferers or a children's charity or something like that, then I think I'd be very hard hearted to not consider taking part in it." He said.
