Sardona-Welterbe-Weg Etappe 5
HARD (3.1/10)Val Sax → Biiflen
A demanding mountain route — the Sardona-Welterbe-Weg Etappe 5 packs 22.8 km and 816 m of climbing into a 7h 26min day. Running from Val Sax to Biiflen, the trail spans an elevation range of 974 m to 2,454 m.
The route breaks into 5 segments. The toughest stretch is the 2.1 km from Val Sax to Älplichopf, climbing 215 m — an unrelenting 102 m/km grade. In contrast, the 10.0 km from Alp Ramin to Biiflen is much gentler — mostly downhill with 920 m of descent.
About 71% of the trail is runnable, but the remaining steep sections will push most people into power-hiking mode. Some pitches hit 60% gradient, so trekking poles are strongly recommended.
Budget roughly 3,977 kcal of energy expenditure and 4.5 L of water. Aim for 60–90 g of carbs per hour to avoid bonking on the longer climbs. No confirmed water sources along the route — carry all the water you need.
