It’s the halfway point in the race across Canada. As the teams take to the ice flows of Hudson Bay, they cross from the province of Manitoba to territory of Nunavut, an area the size of Western Europe, inhabited by the Inuit. The ice is a hunting ground for seals and the polar bears who like to feed on them, it is also a favourite summer holiday spot for beluga whales.
The next leg will take them from the edge of the Arctic to the shore of the Great Lakes – to the fifth checkpoint over 3,000 kilometres away on Manitoulin Island. Situated in Lake Huron, it is the largest Freshwater Island on the planet and is vast enough to contain over a hundred inland lakes itself.
