A PROUD mum says her "inspirational" brother helped her family raise tens of thousands of pounds during a mountainous walking challenge.

Caroline Twiston-Davies and her three daughters, Antonia, Sophie and Zoe, completed a non-stop 56 mile trek through the Brecon Beacons, lasting 21 hours.

Mrs Twiston-Davies, who lives in Much Dewchurch, said the inspiration behind the walk is her brother, Charles Suffield, 60, who has Motor Neurone Disease.

Between them, the women have raised a remarkable total of £116,000.

"It was great. The best thing was that my brother was there as well," said Mrs Twiston-Davies, 53.

"We all chatted and kept each other going.

"He said he was so thrilled we had done it.

"It's good that something so positive can come out of a negative situation.

"I'm so thrilled to have done it."

Making up the group was Mrs Twiston-Davies' daughters, 26 year-old Antonia, Sophie, 23, who live in London, and Zoe, 21, who lives in Bristol.

The challenge was called Trek Fest and took them through the famous mountains over the Welsh border, down to Merthyr Tydfil and back. Their group came 26th out of 700.

Mrs Twiston-Davies says she hopes to raise the profile of the Heaton-Ellis Trust which is looking into a cure for Motor Neurone Disease.

"It's a horrible, muscle-wasting disease," she said.

"You can't walk and there's no cure.

"Charles, who lives in Norfolk, was the inspiration behind it all.

"He has got so many friends. They always say 'what can we do to help?'

"I thought this would be one way they could show their support, and they certainly did.

"The Heaton-Ellis Trust is thrilled with the donation."

Motor Neurone Disease is a progressive disease that attacks the nerves in the brain and spinal cord, leading to muscle wastage.

There is currently no cure and only one drug that may increase life expectancy by up to four months.

"Charles and his wife Emma and their family are an inspiration in the way they are dealing with this disease," added Mrs Twiston-Davies.

"I know he would move mountains for me, let alone climb them."
