Why Parkinson's UK?
My 88 year old father was struck by Parkinson a few years ago. Every day he goes on a walk to counter this disease. As a runner, I wanted to use that inspiration, and help fundraise to fight this disease long-term. I’m therefore taking part in the Royal Parks Half Marathon 2026 to raise funds for Parkinson's UK.
