Course DNA

The Course

Wildstrubel runs 110 km through Crans-Montana, Switzerland. +18,301 ft gain and -18,300 ft loss. Surfaces skew 80% trail / 15% jeep / 5% paved. Gemmipass (2,268 m) and Cabane Wildstrubel (2,789 m). High point near 8,977 ft. Low near 3,495 ft. September temps run 32°F to 75°F. The course rewards patience early and punishes rushed descents after mile 34.

The Work

Train for 18,301 feet of climbing across 110 km. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 27 hours total means limited margin: rehearse fueling every 45 to 60 minutes and downhill eccentric work weekly. Technicality 7/10. Build a block that simulates the crux near mile 44.

Kit

September in Crans-Montana, Switzerland: plan for 32°F to 75°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 27 hours pushes past dark. Poles help on sustained climbs above mile 17. Vest capacity for 2 liters minimum. Shoes matched to 80% trail: lugs for mud, rock plate if the course turns technical after mile 34.

Race Day

Hold effort through mile 17. The field often splits on the first big climb after mile 34. Gemmipass (2,268 m) and Cabane Wildstrubel (2,789 m) near mile 44 is where time is won or lost. Walk the steep pinches. Run the flats and gentle downhills. Crew at major aids: socks, calories, ice if hot. Transitions under 5 minutes when possible. Final third is 23 miles of fatigue management. Finish with reserve for the last descent.
