A group of runners are set to take on 24 park runs in one day in a bid to raise £10,000 for the Northern Ireland Children's Hospice.
Fifteen members of the Mallusk Harriers club in Newtownabbey, Co Antrim will push themselves to the limit during the epic challenge on June 29.
Starting out from East Strand Beach at Portrush on the north coast, the team will tackle 5km courses across Northern Ireland before finishing 24 hours later in Enniskillen, Co Fermanagh.
Their exhausting, round-the-clock itinerary works out at the equivalent of completing three marathons.
With the charity's Horizon House centre located in Newtownabbey, club members regularly pass by on training runs.
They have also been briefed on the work it does in providing services to youngsters with life-limiting and life-threatening illnesses.
Mallusk Harriers' chairman, Neil Campbell, said: "It was an easy decision for us to raise much needed funds for them."
The 15-strong group of men and women have been through a gruelling programme of preparation.
Runs on the Mournes, Divis and the Black Mountain, Cavehill overlooking Belfast and the hills along the east Antrim coast were completed to build the necessary strength and stamina
Confirming the £10,000 goal, he added: "We'd love everyone's support by running with us at any of our runs, and of course by donating to the Northern Ireland Children's Hospice."
