EX and serving police officers will face a gruelling 30-mile challenge alongside Royal Marines this summer.

The Cops 30 Miler will replicate the Dartmoor trek Royal Marines recruits must complete to get their green beret. Participants have to carry a 32lb backpack, water and necessities and aim to get from Kirknewton to Alwinton, in Northumberland, in eight hours.

They will raise funds for the Care of Police Survivors and The Royal Marines Charity. Since the event began in 2016, it has raised £44,000.

Durham Constabulary's Detective Chief Inspector Lee Gosling, who devised the event with West Midlands Police Inspector Simon Guilfoyle, said: “Every year I am inspired by the effort, personal battles and triumph which characterises this magnificent event. It’s an unforgettable day of achievement and exertion, amidst the beautiful and unforgiving terrain of the Cheviot Hills. The amount of officers willing to step up to such a big challenge in aid of two incredible serviceperson charities is humbling. They are not athletes but have a grit and determination to be proud of. Training starts now.”

The event will be held on September 14 and 35 of the 50 available spaces have been filled. To apply for a place or to volunteer email admin@cops30miler.org and to donate visit justgiving.com/campaign/cops30miler2019
