My name is William Newby Grant, I am 12 years old and I am passionate to save the world's animals and our planet.  I am raising money by running 5km every single day for 100 days, no matter the weather, how tired I am or how bad my asthma is.  All donations will go to the WWF and be greatly appreciated.

WWF is at the heart of global efforts to address the world’s most important environmental challenges: protecting endangers species, safeguarding the natural world, tackling climate change and enabling people to use only their fair share of natural resources. Together we can build a future where people and nature thrive. Your support is much appreciated. Find out more by visiting wwf.org.uk
