A CHEMISTRY student is preparing to run the London Marathon in memory of his dad.

Oliver Walker, 22, of Great Bromley, will take on the 26.2-mile challenge to raise money for the Anthony Nolan charity, which enabled his father Steven to live for 12 years after being diagnosed with an incurable cancer.

Steven was diagnosed with multiple myeloma, a rare type of blood cancer, in 2004 and given three years to live.

But Anthony Nolan found him a stem cell donor and that, along with chemotherapy, meant he lived for another 12 years. He died last year, aged 57.
