A fundraiser called 'Speedo Mick' who walks around Britain in just a pair of swimming trunks has made it to the top of Ben Nevis.

Michael Cullen, 58, reached the summit of the UK’s highest mountain wearing only his blue speedos and walking boots at 2pm on Monday after a five hour climb.

He has raised more than £800,000 for charity in the last seven years, walking from John O'Groats to Land's End in 2019 and 2020 and swimming the English Channel in 2014.

But he is set to hang up his blue trunks so he can spend more time with his family.

He hopes his last big challenge - to walk 1,000 miles from John O'Groats to Land's End - will take the total to more than £1million.

As part of his final walk, he planned to scale Ben Nevis, Scafell Pike, and Mount Snowdon along the way.

Mick said he nearly scaled Ben Nevis in a kilt and top – but decided to give it a go in his trunks and couldn’t believe he made it to the top in minus 18 degree weather.

Mick, from Liverpool, said: "I reached the top about 2pm yesterday, I climbed it in five hours, which I thought was pretty good going."

"It was minus three at the bottom at minus 18 at the top with the wind chill."

"I was freezing but I had lots of stuff with me in case of an emergency, and I was with a guide – we took all the precautions we could."

"I actually thought about climbing it in a kilt and a top but when we got there I thought let’s just see how far I can get in my speedos."

"And I managed to walk the whole way in them which I couldn’t even believe myself."

"It was unbelievable, and such a huge achievement."

"I left a few tears at the top of Ben Nevis."

"I am just so grateful to have my life and that I can do stuff like this. "

"I have been sober for 20 years and I got my life back, I hope raising awareness of mental health and suicide prevention can help other people."

"I saw a man when I was climbing back down the mountain, he had seen me going up and asked if I had done it, when I told him I had he said I was an honorary Scotsman now."

"So today I have a kilt and sporran on for walking today."

Mick has walked around 200 miles so far.

He covers 15 miles a day in around seven hours, with lots of people stopping to talk to him and take pictures.

So far Mick has raised nearly £50,000, for the The SpeedoMick Foundation.

The charity will give grants to small charities that support mental health awareness, disadvantaged young people, and the homeless.

Mick added: "I have done about 200 miles of the walk so far, so still got a long way to go."

"I do about 15 miles a day which takes roughly seven hours, we only have so much daylight to walk in."

"I can stomp along pretty fast, especially when it’s so cold."

"People are always stopping to talk and take photographs."

"The hospitality in Scotland has been second to none, everyone has been fantastic."
