An ambulance technician is running from Stirling Castle to Edinburgh to raise awareness of Motor Neuron Disease in memory of his dad.
Gregor Miller, 49, who's based at Glenrothes Station, is taking on the charity run along with some well known sporting personalities, including Hearts' Ryan Stevenson and Watsonians & Scotland Rugby Union's Scott Hastings.
His dad, Campbell, a former police officer in Falkirk and Alloa, passed away with the condition two years ago.

The cash raised will go to My Name’5 Doddie Foundation, MND Scotland and the Euan Macdonald Centre.
Gregor said: "My inspiration for this event has come from losing my dad to this disease. My dad was diagnosed with motor neurone disease (MND) in May 2017 and passed away in 2019.
"He was a keen sportsman and played football for the police and in later life, until his diagnosis, played golf three times a week. Dad only realised he had a problem when he could no longer grip a golf club. As you could imagine this hit him hard.
"Within a few months he had to retire the clubs, quickly followed by his driving licence. For a man who was never at home due to social events, this was a devastating blow. Living with MND and caring for a sufferer of MND was horrific. Dad was given two years to live and died within two weeks of the two years."
Because of current coronavirus restrictions, just four people can run the route at any one time.
That will leave Gregor and Ryan Stevenson running the entire 40 miles, with the other sporting legends dipping in and out for 4 miles each and all those taking part will complete a lateral flow coronavirus test before they run.
