The officers, who are all based at the Chatsworth Road police station, hope to raise £500 for the charity, which offers palliative care to patients, their families and carers.
Helen Green of the neighbourhood central policing team, was determined to participate in the event on June 21.
She said: “The team, the Chatsworth Ladies, is really excited about the challenge. We will be walking 13.1 miles through Worthing and along the Sussex coastline to raise vital funds for this amazing charity. The aim is for all of us to complete the distance with no ‘cop outs’.”
