I have supported Cancer Research Wales now for many years on a personal basis and through my work at Park Plaza Hotel in Cardiff. This is going to be a massive challenge for me and I really want to reach my target and exceed it for this wonderful charity who are funding vital research and are based in Wales. My training pack has arrived and includes in Week 1 a 8 hour walk !! I have been 'warned' that a typical day will involve 8 hours of trekking! As we climb higher, the air gets thinner and at 4,800m (which is the highest point on the trek), the atmospheric pressure is about 50% of that at sea level! I wouldn't be lying when I say this will be my toughest fitness challenge to date!
