Wild 110

Race strategy

Hold a steady pace and save energy for every section.

• 1050m descent. Go easy, save your quads.
• Steep 53% wall. Control your pace and stay focused.
• The finish is runnable. Save your legs to run it all the way.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Ease into the early runnable section, save your quads on the descents until 75.9km, then run your race pace.
• Start · 0.0km–1.4km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.4km–12.7km · Plus 1 more climb. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
• Work · 12.7km–57.6km · Descent of 1050m averaging 12%, descent of 1035m averaging 10%, descent of 1129m averaging 18%. Plus 2 more climbs. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. Running pays off here: run wherever you can. Hike the steepest pitches.
• Fade · 57.6km–102km · Climb of 1125m, descent of 980m averaging 14%, climb of 1704m, high point 2762m. Plus 1 more descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. At altitude your pace drops, and that's fine. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 102km–110km · 8.0km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.

Summits

The highest summit on the course is Blattihubel (2189m), 86.8km from the start. The course also passes close to Sillerenbühl (1976m).

Poles

Trekking poles are strongly recommended: about 18.2km of the course is steep enough for them to pay off.

Quad damage

Quad damage risk is high (index 64 of 100), with 53% of the load in the first half: 4 critical descents, the last of them run on already damaged legs. Downhill-specific preparation and a controlled early pace pay off here.

• Ease into the early runnable section, save your quads on the descents until 75.9km, then run your race pace.
