Members of Northumbria Police and the Tyne Detachment Royal Marines Reserve Scotland tackled a gruelling 30-mile challenge on Saturday.
They took on the fund-raiser carrying 32lbs of equipment, starting at Kirknewton and finishing at Alwinton.
The event, in aid of Care of Police Survivors and the Royal Marines Charity, raised more than £4,000.
Chief Inspector Lee Gosling said: “I’m really proud of everyone who took up the challenge and had a go, they all gave 100% and best of all we’ve raised a lot of cash for great causes.
“I’ve got the blisters and aches to prove it, gruelling just doesn’t do it justice we ran in full on downpour conditions climbed over 5,000 feet over pretty brutal terrain.
“I’d like to thank the Marines who took part and the many others who supported us along the way, to shout their encouragement and give us a very welcome barbecue at the end.”
“We’re hoping to organise another similar event next year and if you’d like to take part go to the following link.”
Of the 18 participants who started, 10 were able to complete the full 30 miles, two were withdrawn due to injury and six who reached their personal limits had to step down.
The route, logistics and medical support were planned to meticulous detail by the men of RMR Scotland: Tyne Detachment, led by Captain Andy Dyer. Around 30 Marines were directly involved during the day, running alongside participants and setting the pace whilst navigating, monitoring progress and safety.
Captain Dyer commended all who took part, saying, “Whether or not someone managed to complete the full 30 miles, it is a real achievement to carry that amount of weight, at that pace, across such extreme terrain and in such horrible weather.”
The two charities benefitting are, COPS, dedicated to helping the families of police officers who have lost their lives on duty and the Royal Marines Charitable Trust Fund provides support to both serving and veteran Marines.
