Race strategy

Hold a steady pace and save energy for every section.

  • Steep 29% wall. Control your pace and stay focused.
  • 693m descent. Go easy, save your quads.
  • 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 30.6km, then run your race pace.
  • Start · 0.0km–2.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.1km–20.9km · Descent of 296m averaging 10%, climb of 629m. 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. Hike the steepest pitches.
  • Work · 20.9km–30.6km · Descent of 693m averaging 7%, high point 576m. This is where the race is built: steady, solid effort. This descent is hard on the legs: short steps, stay in control, poles if you have them.
  • Fade · 30.6km–56.9km · Plus 1 more climb and 2 descents. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. 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 · 56.9km–63.1km · 6.2km 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.
