My nan (who is 71) along with some other of our family members (including me) are doing the Velocity zip wire on the 3rd September at Zip World Penrhyn Quarry Bethesda. We are raising funds for the Haematology unit and accommodation for families to stay in when their loved ones are receiving treatment at Queen Elizabeth Hospital Birmingham. My aunty Sally had a stem cell transplant here two years ago and is now doing amazingly well!
