Billy Clark is only 10 months old—but has already been through five operations in his young life.

The tiny tot was born with bowel problems and was then diagnosed with the life-threatening Cystic Fibrosis.

Now his mum Angela is trying to raise money for research to help find a cure.

The 31-year-old from Tiller Road in Cubitt Town, Isle of Dogs, is taking part in the women’s only 5k race in Hyde Park for the Cystic Fibrosis Trust next month.

“I’ve never run anything like this before,” she said. “My friends suggested running to raise money for research—I didn’t hesitate and signed up straight away.”

Cystic Fibrosis is one of Britain’s most common, life-threatening inherited diseases and claims two young lives every week. It is caused by a defective gene that results in lungs and digestive system becoming clogged with mucus, leading to chronic inflammation and difficulty absorbing food. There is no cure at present.

“I wanted to do whatever I could to help find a treatment,” Angela added. “One day they might find a cure.”

A clinical trial is due to start next year if �6 million can be found. Money raised will also help provide support and care for 9,000 babies, children and adult sufferers in Britain today.

Angela hopes to raise at least �500 from the sponsored run on September 11. She can be sponsored online at http://www.virginmoneygiving.com/team/btk
