Dog Sled racers have embarked on the final stages of la Grande Odyssee challenge high in the French Alps.
The race is an 11-day trek over a 670 Kilometres course which organisers say feels more like 1,000 Km for the Dogs and their handlers because of its 20,000 meter elevation.
Set among snow-capped mountains between Savoie and Haute-Savoie in France, 500 Dogs have been racing across the Alps in a series of challenges.
Vondrak overtook Coste to become the overall leader in the challenge.
The Champion will be crowned in the final stage Bonneval Sur Arc.
