Race strategy

Hold a steady pace and save energy for every section.

  • 889m descent. Go easy, save your quads.
  • Steep 44% 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.
  • Control your HR on the first mountain, save your quads on the descents until 67.8km, 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–18.1km · Climb of 840m, descent of 889m averaging 10%. 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 · 18.1km–46.2km · Climb of 1138m, descent of 1212m averaging 15%, climb of 1302m, high point 2316m. 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 · 46.2km–93.6km · Descent of 776m averaging 13%, descent of 1281m averaging 15%, climb of 1127m. Plus 1 more climb and 1 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. 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 · 93.6km–101km · 7.7km 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.
