A TV star is set to arrive in Wales after a month away as part of a charity trek.

The Traitors finalist Andrew Jenkins is walking 1,200km over the course of 42 days to raise money for Headway, the brain injury association.

This route is believed to be the first of its kind for a charity trek.

Mr Jenkins' journey began on September 29 at the Scottish castle where the BBC show, The Traitors, was filmed and will end at Cardiff Castle in November.

The challenge marks a significant milestone for Mr Jenkins, who was told he may never walk again after a 'serious road accident' at the age of 21.

The accident left him with a brain injury and ended his rugby career.

However, Mr Jenkins made a full recovery and was described by doctors as a 'miracle patient.'

Now, 25 years later, Mr Jenkins is on his feet raising money for Headway to support their work with brain injury survivors and their families.

He is also using the trek to highlight mental health challenges, particularly among men, having experienced periods of poor mental health himself.

As part of the trek, Mr Jenkins plans to deliver wellbeing and mental health talks to various sports and community groups along his route.

He said: "I am so enjoying seeing all these great places along the route, and meeting some lovely people along the way.

"The scenery has been incredible.

"Headway does incredible work to support survivors of brain injuries and their families as it can have a huge impact on all of their lives too as my family and I found out following my accident.

"I’m delighted to be able to raise awareness and funds for their vital work through the trek.

"I’m also undertaking this challenge for everyone out there who has been told they can’t do something, who think they can’t achieve anything, and who have lost their self-belief.

"I want to show them that even though life can feel impossibly hard at times, there’s always a way forward – literally one step after the next can take you a long way.

"And I want to show people that talking about how we feel helps us move through the challenging times, as well as showing others who might be feeling the same that they are not alone."

Mr Jenkins' walk has already taken him through Scotland, Northern Ireland, and northern England.

In the next 10 days, he will visit Wrexham and Powys, making stops at Chirk Castle, Arddleen, Montgomery Castle, Knighton, Gladestry, and Talgarth.

On November 1, he will give a free talk at Wrexham AFC about his journey and offer advice on supporting positive mental health.

Jen Murgatroyd, Headway’s director of fundraising, said: "We are immensely grateful for Andrew’s dedication and efforts in taking on this challenge for Headway.

"The money raised will go towards things like our Emergency Fund that helps family members be at the bedside of their loved one in critical care, or our nurse-led helpline that provides essential information and emotional support to brain injury survivors and their families.

"We are proud to have Andrew champion our cause and I’m sure his journey will give hope and inspiration to other brain injury survivors."
