A local dad who saved a stranger's life through a stem cell donation is now taking on a gruelling coast-to-coast challenge.
Graeme Thomson, 42, from East Kilbride, was a match for a man in England who was battling blood cancer and was in desperate need of a stem cell transplant.
Graeme, who works as a project manager in construction and is a father-of-three, said: "He wrote to me to say thank you, and to let me know that the transplant had saved his life.

"He had been thinking about how to say goodbye to his children, which, as a dad myself, was hard to hear.

"I'm just glad that he never had to do it, he got to go home -- I'm so happy I was able to play a part in that."
Now, Graeme is raising funds and awareness for DKMS UK, the blood cancer charity that contacted him after he joined the stem cell donor register.
He is taking on a 100-mile coast-to-coast challenge across Scotland from Nairn to Fort William.

Bronagh Hughes, spokesperson for DKMS, said: "What Graeme is doing is absolutely amazing.
"His stem cell donation totally transformed the lives of a family, and we are so glad that he has decided to support blood cancer patients yet again by raising funds and awareness for DKMS UK."
Only seven per cent of the eligible UK population is currently registered as stem cell donors, and just 60% of patients find a match.
Graeme said: "I hope that this will encourage everyone to get on the stem cell donor register.
