The Police Get Active Challenge 2021 kicks off later this month and officers across the South Wales force are being urged to register to take part.
Organisers said the challenge, which raises funds for Police Care UK, would give participants the chance to boost their own fitness and wellbeing while supporting a vital cause.
The month-long challenge gets underway on 28 June and officers who take up the challenge can do any sort of physical activity from a 1km walk to running a marathon, swimming, joining a gym session, taking part in an exercise class or venturing out on a bike ride.
They can then log their progress on the Get Active Challenge website or mobile apps.
Those who take part can raise funds as part of their challenge by setting up a Just Giving or Virgin Money Giving page and asking family, friends, colleagues and workplaces to sponsor them.
The money raised will go directly towards improving the lives of police officers injured or killed on duty, and their loved ones.
Everyone who takes up the Get Active Challenge will receive a special commemorative police challenge coin.
South Wales Police Federation chair Steve Treharne encouraged members to go online to register and take part.
Steve said: “The Get Active Challenge is a great idea and gives members the opportunity to boost their own physical and mental health by getting a bit of extra exercise and raising much-needed funds for a cause which is close to all our hearts.
“People who get involved can do as much or as little as they please but I would encourage everyone to sign up and take part.”
It costs £15 to sign up and half the entry fee will go straight to Police Care UK, the charity for serving and veteran police officers and staff, volunteers, and their families who have suffered any physical or psychological harm as a result of policing.
The challenge runs until 26 July and officers can register online.
