If the avalanche risk is too high, or you fancy a change. Then nordic skiing in all its forms: skating, cross country and the nordic variant with metal edges, offers an alternative and a good way to maintain form. With that in mind this video of the Marathon de la Clarée caught our attention with an interesting version of Crazy.
The Marathon de la Clarée is a long distance cross country ski competion now in its 8th edition. It is held in the vallée de la Clarée in the Hautes Alpes. There are 3 distances, 10, 24 and 40km.
