Cancer effects thousands of people. It has affected lots of people around me and will in the future. Cancer Research is one of my favourite charities and any small amount we can give makes a difference.
I also have wanted to do this for years but have never been at the right fitness level. As a personal achievement I would like to try to get to a point where i can not only walk this distance but do it uninterrupted. It should give me motivation to help work towards getting fitter in next few months.
