The multi transition course in North Wales will involve a total of approximately 3.5km of swimming and 12.5km of running (Sprint course is 1.3km of swimming and 4.7km of running). The running route will take in some of Snowdonia’s most stunning scenery and views on mainly off road terrain, including beautiful woodland, a historic monument and a tough climb up into the old slate quarries that tower above the valley.
