Around 100 police officers and staff stepped out in the sunshine to raise cash for charity.
The walkers took part in Mile With a Smile in Durham and Peterlee.
The event, which is now in its fifth year, saw staff running and walking a mile around Durham Constabulary headquarters and at the force's Peterlee warehouse to raise money for this year’s nominated charity, St Cuthbert’s Hospice.
Those staff unable to attend the events have also contributed and walked their mile within their own time.
Four members of staff went an extra 15 mile and carried out a sponsored walk from police headquarters to Seaham seafront in order to raise additional funds.
Deputy Chief Constable, Jo Farrell, said: “We’re delighted with the support we’ve received from across the force. It shows a strong family ethos and a real desire to raise as much money as possible for a great cause.”
Force Wellbeing Co-ordinator, Margaret Toward, said: “It’s fantastic seeing colleagues enjoying walking and chatting with each other as this can be a tremendous boost to their physical and social wellbeing – supporting a great cause makes it even more special."
In excess of £300 has already been raised and donations are still pouring in.
Last year’s event raised money for the Sir Bobby Robson Foundation in memory of PC Gavin Smith, who lost his battle with cancer in 2017.
The money raised will be presented to St Cuthbert’s Hospice at the end of the year once all of the fund-raising events have taken place.
