<p>Me and Alun are going to walk the length of Wales on the old Offa's Dyke path in October. We will walk 177&nbsp; miles in 6 days, carrying tents, food and everything we need.</p> <p>We hope to raise money for the Help for Heroes campaign to assist all those members of the armed services who have been affected by events on active tours of duty.</p> <p>I'm sure most of you know someone who&nbsp;has been affected in some way by in recent years.</p> <p>So please dig deep and donate now.</p>
