Race strategy

Hold a steady pace and save energy for every section.

  • 980m descent. Go easy, save your quads.
  • Steep 34% wall. Control your pace and stay focused.
  • High point at 2761m. Control your HR at altitude.
  • The finish is runnable. Save your legs to run it all the way.
  • Control your HR on the first mountain, save your quads on the descents until 18.6km, then run your race pace.
  • Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.9km–18.6km · Climb of 593m, descent of 980m averaging 14%. Plus 1 more climb and 1 descent. 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. Hike the steepest pitches.
  • Work · 18.6km–32.1km · Climb of 1705m, high point 2761m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. At altitude your pace drops, and that's fine. Hike the steepest pitches.
  • Fade · 32.1km–45.2km · Descent of 1405m averaging 11%. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. 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 · 45.2km–53.1km · 7.9km 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.
