something really special for the Alzheimer's Society.
This 50km looped route covers some of the best of the Chilterns countryside. You can Walk, Jog, or Run along historic trails and
over rolling hills. Starting & finishing at a Base Camp in Henley Showground, there's a Saturday night celebration BBQ &

real variety, and some wonderful scenery - and it's all easily accessible from London. With 25km and 10km challenge options
