Traitors star Andrew Jenkins to finish trek at Cardiff Castle

He is raising awareness and funds for Headway, a charity which supports people with brain injuries.

He said the challenge was “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,” he added.

The final leg of Andrew’s walk takes him through Wales, with stops at Knighton, Gladestry, Talgarth, Brynmawr, Cwmbran and Caerphilly Castle before finishing at Cardiff Castle.

He previously walked through Scotland and northern England, as well as visiting Northern Ireland along the way.

“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,” he said.

“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.”

Speaking to Radio Wales Breakfast from Abergavenny, Monmouthshire, on Friday, he said he had enjoyed the adventure but was excited to reach Cardiff and take a trip to the Principality Stadium to watch Wales play Fiji in rugby’s Autumn internationals.

“The first couple of weeks, we didn’t see anybody because I was in the middle of mountains and forests in Scotland.

“When I came back into Wales it started raining, but apart from that it’s been nice walking weather – not too hot, not too cold,” he added.
