Coronation Street stars Catherine Tyldesley, Katie McGlynn and Tisha Merry are taking part in this year's TrekFest challenge, a 50km trek through the Brecon Beacons, to raise money for The Joshua Wilson Brain Tumour Charity and Parkinson's UK.

Tyldesley said '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'.
