Race strategy
Hold a steady pace and save energy for every section.
- 825m descent. Go easy, save your quads.
- Steep 38% 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 56.9km, then run your race pace.
- Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.3km–8.7km · 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. Hike the steepest pitches.
- Work · 8.7km–65.3km · Descent of 483m averaging 8%, descent of 825m averaging 9%, descent of 737m averaging 8%. 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 · 65.3km–94.1km · Climb of 434m, high point 896m. Plus 1 more climb and 2 descents. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
- Home · 94.1km–114km · 19.9km 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.

Poles
Trekking poles are strongly recommended: about 12.6km of the course is steep enough for them to pay off.
Quad damage
Quad damage risk is high (index 56 of 100), with 50% of the load in the first half: 3 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 56.9km, then run your race pace.
