One of the reasons I started this challenge is because I care deeply about nature and the Earth. I worry about what will become of all the wild living creatures and what kind of world my grandchildren will live in - will there be any tigers, elephants and rhinos left to see in 25 years?

Also feeling low and unmotivated since July, for several reasons, I decided a physical challenge could help me get moving and realise I have a lot more physical power than I think, as well as support a good and necessary charity.

Will you join me in supporting a good cause? I'm raising money for WWF and your contribution will make an impact, whether you donate a lot or a little. Anything helps. Thank you for your support, not just for the charity but for me also. I always hope to inspire others in my quest for making the most of life.
