Karen Ennis is taking on the Oceans Seven Swimming Challenge to raise £100,000 for Alder Hey.
The Oceans Seven is a marathon swimming challenge consisting of seven open water channel swims and covering 123.5 miles. It was devised as the swimming equivalent of the Seven Summits mountaineering challenge. It includes the North Channel, the Cook Strait, the Molokai Channel, the English Channel, the Catalina Channel, the Tsugaru Strait and the Strait of Gibraltar.
