My goal is to walk from Land's End to John o' Groats and raise as much funds for Alzheimer's Research UK in the process in honour of my late Grandfather Terry Darker, who passed away from the disease recently.

Every 3 minutes dementia steals a happily ever after. Research is our only chance of changing the ending for people affected by dementia.

We are the UK's leading dementia research charity. We exist for a cure.

Your donation helps our scientists and researchers find new ways to diagnose dementia, develop new treatments and find a cure for dementia.
