La Grande Odyssée Savoie-Mont-Blanc is intended for mushers with teams of 14 dogs who are experienced in long- and middle-distance.
Using a GPS tracking system, spectators can visit the race's website to follow in real time the mushers' progress.
Each itinerary is simulated in 3D as a "virtual walk around" realized with the help of a camera positioned to follow a precise path along a track or sled trail.
For 2011, Finnmarksløpet in Norway and La Grande Odyssée Savoie Mont Blanc in France decided to create a new championship called the Arctic Alps Cup.
It follows the trails of the Espace Diamant that join the Franco-Swiss massifs called Portes du Soleil, the Haute Maurienne Vanoise and Megève.
