Race strategy

Hold a steady pace and save energy for every section.

• 722m descent. Go easy, save your quads.
• Steep 33% 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 101km, then run your race pace.
• Start · 0.0km–1.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.7km–12.4km · Climb of 715m. 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 · 12.4km–58.7km · Descent of 722m averaging 9%, climb of 749m, descent of 883m averaging 11%. 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.
• Fade · 58.7km–101km · Climb of 1881m, high point 2166m, descent of 911m averaging 8%, descent of 1321m averaging 10%. Plus 1 more climb. 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. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 101km–120km · 18.5km 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 13.4km of the course is steep enough for them to pay off.

Quad damage

Quad damage risk is high (index 57 of 100), with 42% 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.
