His knee ligaments are torn but Kevin Walker has vowed to crawl across the marathon line in honour of brave cancer girl Alice Bullock.
Alice who was 18, lost her battle with a cancer in November 2008.
The Beyton teenager, who was a pupil at Thurston Community College had been diagnosed with Rhabdomyosarcoma two and a half years earlier.
Her mum Sonia has already raised about £25,000 for the Teenage Cancer Trust unit at Addenbrooke’s Hospital, now Sonia’s partner Kevin, 50,is preparing to run the London Marathonnfor the same cause.
“Alice was the most determined person I think I have ever known.
“She was told from the start that the outcome was not looking positive.
“She ignored all that and just threw herself into her life.
“She just set herself goals whether it was going to a concert or visiting a friend or her school work.
“She was determined, she never gave in and I think that extended her life.”
Kevin is running the marathon despite torn ligaments in his left knee, and ‘the effects of age’ in his right.
“Even if I have to crawl it, I shall do it,” he said.
