I am taking on the Chiltern Challenge in my father-in-law's memory and raising funds for the Alzheimer’s Society. I will be attempting to walk 100km, without stopping to sleep, over a surprisingly bumpy route that takes me from near our home to near where my father-in-law lived. The Alzheimer’s Society is one of the charities chosen by his family and exists to research into dementia care, cause, cure and prevention.  They are also striving to create a society where those affected by dementia are supported and accepted, able to live in their community without fear or prejudice.
