The 63-year-old has wanted to take on the 630-mile challenge since he read about it 20 years ago, and now he plans to start out the long journey from Minehead, Somerset to Poole, Dorset, the day after his birthday on April 1.
The retired mechanical transport technician in the RAF said: “It’s my mountain in life. I thought it was a good opportunity to raise money for Help for Heroes and Wiltshire Air Ambulance.
“It just seemed to be a good time to do it now I am retired and have some more time.”
