Wishing to run across the Triglav, Dolomites, Tyrol, la Bavaria, Interlaken…, they decided to follow a combination of the red and green Trail of the Via Alpina. To limit the overall distance to 1,000 km, they decided to start in the Triglav National Park (Slovenia) and finish in Chamonix (France). From the Triglav, they followed the Red Trail across Italy, Austria, Germany to Lichtenstein. From there, they switched to the Green trail to Lenk in Switzerland. After Lenk, they made their own trail to Chamonix, France.
