Chris Moon raced across the Sahara

Chris Moon, 41, hopes to complete the 1,284 mile route in 25 days, tackling the equivalent of two marathons a day.

He will walk for 18-hours a day, with just four hours sleep, along a route through many UK towns via London.

The father-of-two, walking for charity, says he wants to show that disabled people have dreams and aspirations.

Achieving goals

Mr Moon, who starts his journey on 5 June, hopes to raise �1m for disabled charity Leonard Cheshire.

He said: "I am keen to show that disabled people have dreams and aspirations like the rest of the population and that we can all achieve our goals, given the right opportunities and support.

"The issue of adult disability isn't one that we are always comfortable dealing with. It's about Leonard Cheshire homes helping disabled people achieve their goals.

"They are good reason enough to put one foot in front of the other, a reason more important than yourself to keep going."

Mr Moon lost his lower right arm and leg while walking in a supposedly mine-cleared area in Mozambique in 1995.

A keen runner before the accident, he ran the London Marathon within 12 months of leaving hospital and has completed the 250km Saharan race Marathon des Sables, run the length of Cambodia and climbed Kilimanjaro.

During the walk he will be researching the limits and efficiency of prosthetic limbs, using his own state-of-the-art leg.

A professional motivational speaker who has been walking and running to train, he says he is fit and mentally prepared for the challenge - despite being warned it is not physically possible.

"I have always thought it would be quite nice to walk the length of the land, but to do it for one of the charities I support," he said.

"Everybody facing a challenge in their life can deal with it if they have a mind to.

"I can't say 100 per cent that I will do it but it's about doing the best I can.

Survival plan

"The important thing to be able to survive it is to plan to slow down, to be injury free and go the distance."

A number of celebrities as well as friends and family will join him on parts of the route to the Cornwall coast.

And he is confident he will get there.
