Race strategy

Run easy on the first mountain, then go all out on the second.

• 324m descent. Go easy, save your quads.
• Steep 26% wall. Control your pace and stay focused.
• Final 742m 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 mountain, save your quads on the way down from it until 9.1km, then run your race pace, and start the final descent from 42.4km under control, then go all out near the bottom.
• 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–9.1km · Descent of 324m averaging 10%. 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. This descent is hard on the legs: short steps, stay in control, poles if you have them.
• Work · 9.1km–34.4km · This is where the race is built: steady, solid effort. Running pays off here: run wherever you can. Hike the steepest pitches.
• Fade · 34.4km–42.4km · Climb of 647m, high point 529m. 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. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 42.4km–53.8km · Descent of 742m averaging 7%. 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.

Quad damage

Quad damage risk is moderate (index 27 of 100), with 40% of the load in the first half: 1 descent deserves a plan and a couple of downhill sessions before race day.

• Control your HR on the first mountain, save your quads on the way down from it until 9.1km, then run your race pace, and start the final descent from 42.4km under control, then go all out near the bottom.
• #1 · 5.7–9.1 km · 324 m D−, -9.6% · 44.7 km ahead → control
• 42.4–53.7 km · 742 m D−, -6.6% · 0.0 km ahead → even, first half under control, let go at the end
