He’s 6ft 9in, weighs 31st and pulls trucks with his bare hands for fun.

But the World’s Strongest Man Hafþor (Thor) Julius Bjornsson has revealed even he is trolled on Twitter.

Thor – who plays Gregor “The Mountain” Clegane in hit show Game Of Thrones – said that he has never been challenged to a punch-up in person.

But the Icelandic giant is forced to regularly block tormentors who target him on social media.

Thor – who will meet fans at the Carmunnock International Highland Games, near Glasgow, today – said: “I don’t get people asking me to fight face-to-face but there’s a lot of brave folk on the internet.

“No one has ever threatened me in real life but on Facebook and Twitter it's all the time.

"You just get internet warriors.”

Thor caused a stir on social media when girlfriend Kelsey Henson posted photos of them together on Instagram.

The pair have been dating since September and, asked how they kissed, Kelsey joked: “He bends, I tiptoe.

"Or just say, ‘Screw it, pick me up’.”

And Thor said: “People try to be rude against me, my family, my girlfriend, anything.

“People like to be mean to people through social media. That’s what people do today.

“If there’s anything that offends me, especially if it’s towards my family, I just block them.

"I don’t accept that.

"I don’t get upset because I like to focus on the positive.

"I’m the world’s strongest man.

"What have they achieved?”

The 29-year-old is looking forward to his first trip to Scotland.

He added: “I’ve always wanted to visit, I’m delighted to get the chance.

“My hero Jon Pall Sigmarsson was always training there and now finally I get to see Scotland and see the famous Highland Games there.

"He passed away many years ago but he was a big influence for many kids in Iceland and he inspired me.

“As a kid, I could believe I could one day be the world’s strongest man because Jon Pall opened the doors for us by winning the title four times.

“Now I’ve finally won it and I’m very excited to go to Carmunnock Highland Games and meet all the people there.

"I’ve tossed a caber before and I’m very good at the weight over the bar event.

"I’m just going to have fun.”

Thor almost eats an astonishing 1.2kg of steak each day.

He said: “It’s a lot of work and a lot of eating.

"I wake up around 7am and have six eggs, six pieces of bacon, a glass of orange juice and a big glass of hot water.

“Then, two hours later, I have 400g of rice with 200g of steak and repeat the same meal every two hours after that.

"I add some carrots or red peppers to it and always take on a lot of water as well.

“Sometimes you get tired of eating all the time and it’s hard.

"But my body is my work.

"I have to eat those steaks to become stronger so I just eat them. I’ve eaten a few cows in my lifetime.”

Former basketball player Thor starts filming season eight of Game Of Thrones next month.

Fans are desperate for them to have a square go in a hotly anticipated “Cleganbowl”.

Thor said: “Rory and I are actually very friendly.

"I like him a lot.

"I cannot go into details about whether our characters will fight because I'm busy filming next month and I’m not allowed to talk about it.

"They make you sign a contract.

“Acting just came to me.

"They reached out to me and I’m obviously happy to be part of Game Of Thrones.

"Maybe after my strongman career, I’ll focus more on acting. Who knows?

“I get recognised a lot from Game Of Thrones and Strongman.

"People who call me ‘Bjornsson’ are people who know me from Strongman.

"If I hear someone screaming, ‘Yeah, The Mountain’, it’s a Game Of Thrones fan.”

Thor is celebrating finally being crowned the World’s Strongest Man after winning the competition in Manila, in the Philippines.

And he revealed he was victorious despite breaking a toe just a week before the event.

He added: “It happened just a week before the final.

"I dropped a weight on it and it’s actually still swollen.

“It’s going to be swollen for the rest of my life because I just kept on going and pushed myself through the pain.

“I had no choice. I had to compete and I remember in the heats it was very painful.

“I was very worried for the truck pull if my toe would cope and I could go through the pain.

“Last year, I tore my quad two weeks before and I didn’t tell anyone about that.

"I was doing squats and, in one of my sets, I tore my quad very badly and there was blood everywhere.

“I was very scared. I thought, ‘I’m going to World’s Strongest Man in two weeks. What can I do?’

"Doctors in Iceland said it needed 12 weeks to heal.

"But I needed to compete.

“I flew to Boston for blood treatment that helps you recover much faster than normal and was runner-up.
