Richard, a dad-of-three, will be running 50 miles a day, starting in John O’Groats on the north eastern tip of Scotland and finishing in Land’s End in Cornwall.

The self-employed decorator, who has been running 120 miles a week in preparation, starts the challenge on March 20.

“I’ve done ultramarathons in the past, which are up to 50 miles. But I’ve never done anything this stupid,” Richard joked.

“I was supposed to do it in 2018, but I lost my Dad, and then I was injured last year – so I need to do it this year.”

And losing his Dad has played a part in the choice of Nightingale House – which the challenge is raising money for.

Richard, from the Moss area of Wrexham, said: “I’m doing it memory of my Dad and best friend – he died of cancer and Nightingale House cares for so many cancer patients living out their final days.

“I’ve also had friends who’ve spent their last days at the hospice – so it’s a brilliant cause to raise money for.”

And talking about his feelings prior to starting the challenge, Richard said: “It’s more excitement than nerves or trepidation – I’m really looking forward to seeing the whole of Britain for the first time.

“In the car and stuff you can’t get to experience it like you can if you’re out running. I’m more worried about getting injured and having to pull out than anything else.”

So far, Richard has raised over £1,300 for Nightingale House – and you can donate to the fundraiser here.
