Thousands of runners are set to do battle with this year’s Cardiff Half Marathon – but only one will be wearing a full suit of armour.

Tudor Jones, who has been nicknamed ‘Sir Runalot’, will be attempting to set a new Guinness World Record for the fastest half marathon wearing a suit of armour at the race on Sunday, October 2.

The steel suit weighs a whopping 30kg – almost half of Tudor’s bodyweight – and he will need to complete the grueling 13.1-mile race in less than three and a half hours in order to set a world record.

Tudor said: “Training has been challenging, exhausting and painful.

“The problem is the heat from the padding, which is a nightmare after the first hour. Dehydration is the main challenge to face, not the distance.

“I’m now working as a labourer as well and so the training has gotten harder to fit around life.”

The 27-year-old hopes to use the world record attempt to raise £1,000 for the Ty Hafan and Mencap charities and he has been training hard for race day.

He added: “I’ve always been into history and already had a full suit of armour. I had a bit of free time so I thought, why not?

“A friend who works with one of the charities I’ve chosen suggested doing it for charity then a friend dropped the idea of a world record attempt and then it just snowballed from there. Now here we are.”

Mr Jones is one of more than 17,000 runners who have already signed-up for this year’s Cardiff University/Cardiff Half Marathon on Sunday, October 2.
