Officers walked over 30km for the fundraiser.
Gardaí have raised over €10,000 for the Offaly Down Syndrome Association.
Officers and members of staff in the Tullamore Division walked 35km on Saturday, on a journey which took them from Tullamore to Shannon Harbour, along the Grand Canal Bank.
Despite setting a target of €1,000, that goal was smashed, with just under €10,500 raised.
Gardaí say everyone made it to their destination safely, and are thanking everyone for their support over the weekend.
