The Coastal Cancer Challenge will bring competitors over some of the most breathtaking scenery Donegal has to offer. It includes a revised map with a 12km run around McSynes Gun Loop and the Hornhead scenic drive. A 2km kayak across the open sea of Sheephaven Bay. A 42km cycle across the back roads to Muckish Mountain via Ards Forest Park and through the Creeslough/Falcarragh railway line with a trek of 3km up and down the spectacular Mountain in between.
