THREE siblings are running their first-ever marathon together to raise money for Parkinsons UK at the inspiration of their mum.

Mary Roberts of Clarbeston Road, who was a well-known personality in county farming circles, was diagnosed with Parkinson's in 2006 and is now a resident in Blaenmarlais Care Home in Narberth.

"She has been amazing at coping with the disease," said her son Owen, who is taking on the Newport Marathon challenge in April with sisters Anna Jones, aged 44, of Reynalton and Soozy Roberts, aged 34, of Stroud.

"Mum has always been so strong, despite losing her husband to cancer three years ago.

"She is an amazing inspiration, and although she moved into a care home last year, her strength of character still powers on, and we wanted to give something back, so we decided to run our first full marathon."

The trio ran their first half marathon in Cardiff last October for different charities, including Macmillan Cancer Support in memory of their dad Graham and sister Alice.

Meanwhile, their other sister, Margaret Pope of Narberth, had previously raised more than £4,000 for Macmillan from her sponsored headshave just over a year ago.

Added Owen, aged 37, who lives in Hayscastle Cross: "Running a marathon is quite a big step for all of us, but we really want to do it to show our thanks to Parkinsons UK. Mum is really appreciative and supportive of our efforts, which makes it all worthwhile."

Mrs Roberts, a member of the Pembrokeshire Parkinson's Society, which meets weekly at the Hope Centre in Neyland, added: "I hope they will manage to raise a good amount for Parkinson's Uk, a charity which has helped me a great deal."
