While you smash your running goal, the money you raise will get us closer to the goal of defeating dementia.

Your support powers research

Right now there are 850,000 people with dementia in the UK alone, and every three minutes another person develops the condition.

Around every one of those people are friends and family, often struggling themselves to keep life on track. But by participating in Running Down Dementia you give everyone hope by helping to fund vital research.
