David Sagar’s dad John (67) was forced to have a kidney transplant 12 years ago due to a condition called sclerodermititus which attacks the internal organs.
And John now faces a future of dialysis treatment four times a day after the transplant organ failed.
David (38), who lives in Read, signed up for next month’s London Marathon to raise money for Kidney Research UK, which provides hope for people like his dad.
He said: “Twelve years ago, my father was lucky enough to get a transplant and his life changed for the better.
“He was spared the restrictions of dialysis, and got his life back. But sadly, the average life of a transplant kidney is only 10 to 15 years, and my dad’s has now failed, so he must return to dialysis.”
John, who used to own Sagar Brothers Ltd building company, constructed hundreds of houses across East Lancashire, including the Casterton Avenue area, before kidney disease struck.
