Devizes resident Andy Escott had a few cuts to his feet after walking barefoot along the Kennet and Avon Canal towpath.
Mr Escott, 33, walked for six kilometres in his bare feet to replicate the distance that some children in developing countries walk each day to fetch water.
He did the challenge to raise money for international water aid charity Just a Drop’s clean water project in Makueni County, Kenya.
Mr Escott, of Broadleas Park, walked down Caen Hill and finished at the Barge Inn, Seend Cleeve.
He was born with three toes on his right foot which can affect his balance and halfway round he carried a plastic container filled with 25 litres of water.
He said: “The hardest bit was carrying the water which moved around. I had it on my shoulders.
“When I finished I had a few thorns in my feet and a few cuts, but nothing major. It was tough and in terms of exercise it was the hardest thing I have ever done.
“Kids in developing countries carry water containers on their heads every day. I did try to carry it on my head but I wasn’t used to it and couldn’t do it.
“They have to do this every day to get water.
“The money I am raising will go towards building water tanks in their community so they don’t have to do it.
“It will change their lives. I’m really pleased with the amount of support I have received from friends, family, colleagues and clients.”
Mr Escott, who is a Cambridge Weight Plan consultant, was joined by colleagues, a friend and his 12-year-old nephew, Robert Parsons, and completed the walk in just over two hours.
He said the weather was ideal as it was not too hot or cold and the ground was a little muddy from recent rain and he managed to finish the walk just before it started raining.
He trained for the walk by walking barefoot around his estate mainly early in the mornings.
He has raised £800 towards his target of £1,000. Donate at http://www.justgiving.com/be-amazing
