A fundraiser who lost his sister-in-law to an aggressive brain tumour is set to run the London Marathon to support research into the disease.

Adam Ramadhen, who is originally from Sandy, has raised £3,000 and is hoping to reach a target of £7,000 for charity Brain Tumour Research.

Ria Kelly – wife of Adam’s wife, Aissa – died in 2013, aged only 31.

Adam, who now lives in Kent, has never run a marathon before – but he is determined to go the full distance in Ria’s honour on April 22.

“I watched Ria fight this cruel disease with true determination,” said Adam, 31.

“With the odds against her, she still managed to smile every day, be extremely positive and try to bring happiness to all those around her. Her attitude was truly amazing and she had unmatchable strength.

“My motivation is simple. If Ria can fight cancer for four years and still smile every single day, I can do her the honour of running 26 miles in her memory and raise money to help to find a cure for this awful disease.”

Ria was given six months to live when she was diagnosed with dlioblastoma multiforme, a high-grade brain tumour, in 2009. Over four years, she had brain surgery on two occasions, as well as gruelling radiotherapy and several rounds of chemotherapy.

Aissa said: “We all miss my sister Ria very deeply and she continues to motivate and inspire us in life and in the challenges we set ourselves.

“The whole family is supporting Adam in this challenge as we want to raise as much attention and money as possible to help families everywhere who go through the heartache of discovering partners, children, siblings and parents have this cruel disease.”

Brain Tumour Research funds a network of centres of excellence where scientists work on improving outcomes for patients and, ultimately, finding a cure.

The charity’s Tim Green said brain tumours kill more people under the age of 40 than any other cancer, yet just one per cent of the national spend on cancer research goes to this disease.

“For too long, brain tumours have been a neglected cancer,” he said. “We are extremely grateful to Adam for his support. Together we will find a cure.”
