Have you ever fancied raising money for charity by taking part in a charity trek abroad? In September 2018 Great Western Air Ambulance Charity will be heading to China to experience one of the seven great wonders of the ancient world. Over eight days we will trek along the wall, seeing sights and experiences we have never encountered before. We still have spaces to join us – are you up for the challenge? Watch our video clips of Rebecca Hing talk about her experience of taking part in a GWAAC charity trek abroad last year.
