The mum of a member of a swimming group said she's "immensely proud" as they completed 365 swims in a year in memory of her husband.
Margaret Gilgunn's son, Peter, started the fundraiser with the Dunmurry Dippers as a way to raise awareness of a rare form of brain cancer, giloblastoma, after his father Tom died in May after having the disease.
An emotional Margaret travelled to the Colin River in West Belfast from her home in Downpatrick on Saturday to see the group dive into the icy waters in tribute to her husband.
