Well done to Kate Steels from IISA GB on your 8th Ice Mile and the 6th of the ICE 7s.
Kate swum in the mountains of New Zealand in order to find ice waters in the Oceana Continent.
Kate last of the 7s Ice Mile should be in South America. Plenty of ice waters there. High up in tech Andes or down at sea level down south in Patagonian winter.
