Race strategy
Hold a steady pace and save energy for every section.
- 859m descent. Go easy, save your quads.
- Big early climb with 1.7km gain. Hold your pace, save your legs for later.
- Final 1404m descent. Save your legs to go all out on it.
- Long race. Control your HR and effort. Early mistakes cost the most.
- Control your HR on the first climb, save your quads on the descents until 90.0km, then run your race pace, and start the final descent from 93.8km under control, then go all out near the bottom.
- Start · 0.0km–1.2km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.2km–8.0km · Climb of 1410m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
- Work · 8.0km–50.6km · Descent of 330m averaging 21%, descent of 859m averaging 14%, descent of 1057m averaging 18%, high point 2433m. Plus 3 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 · 50.6km–93.8km · Descent of 759m averaging 11%, climb of 697m, descent of 1230m averaging 12%. Plus 2 more climbs. 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. 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 · 93.8km–107km · Descent of 1404m averaging 11%. No heroics: settle back into your own effort and hold it to the line. Very long descent: first half under control, then even, let go only near the end.

Poles
Trekking poles are strongly recommended: about 18.0km of the course is steep enough for them to pay off.
Quad damage
Quad damage risk is high (index 61 of 100), with 45% of the load in the first half: 5 critical descents, the last of them run on already damaged legs. Downhill-specific preparation and a controlled early pace pay off here.
- Control your HR on the first climb, save your quads on the descents until 90.0km, then run your race pace, and start the final descent from 93.8km under control, then go all out near the bottom.
