Beautiful, technical, wild, demanding, there are not enough adjectives to describe the TDS®. Acronym for "Sur les Traces des Ducs de Savoie" (following the footprints of the Dukes of Savoie), the TDS® links the Aosta Valley to the Savoie, allowing runners to discover the villages of the Tour du Mont-Blanc and the mountains that surround them. To cross this unique playground is to walk where history and mountains, the technical terrain and the kindness of its inhabitants blend together.

In addition to its traditional departure from Courmayeur, the new edition of the TDS® takes runners to explore the Beaufortain region. This incredible route winds through the most amazing places of the massif such as Pas d'Outray, with its breathtaking view of the Pierra Menta and Grand Mont - two mythical places for ski mountaineering. Not to mention Hauteluce with its typical hamlets and its breathtaking view of Mont-Blanc. This new TDS® is waiting for you to take on the challenge.

With its unique landscapes, its friendly and alpine atmosphere and its many remarkable viewpoints, the TDS® is more than ever a world-class event and the adventure of a lifetime. It is up to you to come and write the history of this spectacular race ®.
