Royal Marines from 43 Commando have completed a 24-hour marathon challenge, dubbed the 'Moses Mountain Marathon', in memory of one of their former officers.
Major Chris Moses, who served for 13 years, died in January 2020 following an accident as he carried out work as a tree surgeon.
Six marines based at HMNB Clyde twice ran the 13-mile route from the naval base up to the top of Beinn a' Mhanaich mountain and back.
So far, their efforts have raised more than £7,000, to be shared between the Royal Marines Charity and Erskine veterans charity.
Sergeant Major Richard Hayden from 43 Commando was part of the running team.
He told Forces News: "This is quite fitting. This is something that he would have liked to have done and something that we can remember him by.
"We have a foundation of doing very long marches with weight across places like Dartmoor.
"The fact that we are mountain troops, we specialise in this type of terrain, so this sets us up well for the challenge."
Major Kane Holford said on the day of the challenge: "A little bit wet and boggy underfoot but that's not going to stop us.
"I can't speak for the other five runners but it's very much an enjoyable event – booked the weather especially for it!
"So Chris [Major Moses] being quite an adventure athlete was not one to shun these sorts of challenges.
"The challenge that we're doing today is very much in the spirit of how we remember him and if he was here today he would be very much involved."
