What is the Wildstrubel course like?
Runners cross manicured alpine pastures, climb to high passes such as the Gemmi and the Rawyl and drop into glacial valleys with views of 4,000 m peaks. Climbs are long and steady, and descents are steep enough to tire the quads.

How do you fuel the Wildstrubel?
September in the Alps: warm valleys, near-freezing passes and sometimes snow.
- Set your base plan. For a race that takes 12 to 20 hours, 60 to 80 grams of carbs an hour is a common starting point.
- Eat on the climbs. Long uphills give you time to eat. Save drinking and eating for those parts, not the steep descents.
- Plan for cold. In the cold runners drink less and forget to eat. Warm drinks and soft foods help.
- Keep sodium steady. Sweat loss is smaller in the cold but still real in the warm valleys.
