For the challenge he will walk from one office to the other, which equates to around 27 miles.
“I will be walking with my father-in-law, who is a retired colonel for the British army, so I’m sure he will keep me on the right track,” Dan said.
During the challenge Dan will be wearing an old Liverpool FC shirt of his brother’s, which he described as a “treasured possession”.
“Being a Chelsea supporter, I think this will be harder to wear than walking for over nine hours,” he added.
His employers are supporting the walk with a £500 donation via the Edenstone Foundation. The Foundation receives a proportion of the proceeds from every home sold by the Edenstone Group to support good causes.
