In a quintessentially British display of middle-aged determination, four blokes in their late forties are embarking on a mission of both physical prowess and philanthropy.

With the noble goal of completing a walking marathon (26 miles) around the sunny streets of London, they will lace up their trusty trainers, as they march forward in support of Alzheimer's research.

They are fully aware that the journey may span a hefty ten hours, so they graciously welcome any and all donations, recognising the importance of every penny in the fight against this debilitating disease.

Why run, when you can walk!
