I lost both my Mum and Dad within 12 days of each other earlier this year. In the weeks that followed, I needed something that felt worthy of them, a challenge as big as the love I have for them both.

So I'm walking the entire 84-mile Norfolk Coast Path in a single, unbroken attempt. No stopping. No sleeping. Just one foot in front of the other until it's done.

My Mum spent her last days in a hospice, surrounded by extraordinary people who made sure she wasn't afraid. Every pound you donate goes to the hospice services that were there for my Mum when it mattered most. If you can spare anything, it means everything.
