Coronation Street stars swap the cobbles of Weatherfield for a trek through the Brecon Beacons

Coronation Street stars Catherine Tyldesley, Katie McGlynn and Tisha Merry will be swapping the world famous cobbles of Weatherfield for an arduous 50km trek through the Brecon Beacons this summer.The trio, who play Eva Price, Sinead Tinker and Steph Britton, will head out to the mountain range in South Wales on 4 June to raise money for the charity and ultimate endurance challenge, TrekFest.

Taking part alongside friends and family as part of #TeamVital, the ladies have chosen to raise funds forThe Joshua Wilson Brain Tumour Charity based in Manchester, and Parkinson's UK.Corrie actress and HELLO! Online blogger Catherine said: "I'm excited and honoured to be trekking over the Brecon Beacons in aid of these two charities. More research is desperately needed into finding out what causes Parkinson's. I truly believe we are only a matter of years away from finding breakthrough treatments for this cruel condition.

"I'm passionate about completing TrekFest. Our team will train hard to make a respectable time, and raise much needed funds for both charities. We hope to do both of these causes proud, and I'm looking forward to this amazing adventure with a great bunch of friends. "The far-stretching Brecon Beacons offer a beautiful setting for the trek, which is organised by Global Adventure Challenges, at the same time as providing an extreme physical workout.

The actors will cross the highest peaks in the Beacons and South Wales including Pen Y Fan, Corn Du, Cribyn and Fan Y Big, along with thousands of others.

Katie said that she's looking forward to "getting stuck in to the challenge," adding, "there's a great bunch of us who will motivate each other and I'm sure we will have plenty of belly laughs (and blisters) along the way."
