An amputee is completing a series of fast walk challenges to raise awareness of organ donation.
Ronnie McIntosh, from Dundee, suffers from a rare autoimmune condition called Sjogren's Syndrome.
It led to kidney failure and ultimately resulted in the amputation of both of his legs.
Before he became seriously ill in 1993, he was a successful marathon and fell runner.
Now the 61-year-old is taking part in several ‘race walk’ events to call for more organ donors.
He said: "I get the same buzz as I did on a run. You're pushing yourself to the limit to get yourself fit and hopefully that will benefit you in the future.”
This weekend he is taking part in the latest in a series of fast walk events with a 5km challenge in Edinburgh, where he will also promote organ donation.
Mr McIntosh added: "It seems sad that people go out of this life with perfectly good organs that could be used to transplant other people and give other people a new lease of life. You cannot get any better than a second chance of life. That's what I got, a second chance of life - not many people get that."
Staff at the renal unit at Ninewells Hospital, where Mr McIntosh received life-saving treatment, are also raising funds to purchase him a set of artificial limbs designed to take the impact of running.
