Alpe Adria Trail

The Alpe-Adria Trail is an epic long-distance hiking route connecting the foot of Austria's highest peak, the Grossglockner (3,798m), with the Adriatic port of Muggia in Italy. Spanning 43 stages, the trail traverses the Hohe Tauern National Park, the Nock Mountains, the Julian Alps, and the karst plateau of the Friuli-Venezia Giulia. It is designed as a 'discovery trail', prioritizing dramatic landscape transitions from the glaciated high Alps through the 'Emerald' Soča Valley to the Mediterranean coast. While it skirts technical climbing peaks, the total distance and cumulative elevation changes create a significant endurance demand.

Lençóis Maranhenses is a vast field of mobile sand dunes positioned along Brazil's northeastern coast. The landscape is defined by the seasonal accumulation of rainwater in the valleys between dunes, creating thousands of clear freshwater lagoons from May through August. The 43km trekking traverse between Atins and Santo Amaro involves sustained walking across soft sand slopes and navigating between the remote Baixa Grande and Queimada dos Britos oases. The primary challenge is the combination of high thermal stress, intense solar reflection from the white sand, and the physical load of soft-substrate movement.
