Race strategy

Hold a steady pace and save energy for every section.

  • 264m descent. Go easy, save your quads.
  • Final 640m descent. Save your legs to go all out on it.
  • Steep 26% wall. Control your pace and stay focused.
  • Control your HR on the first mountain, save your quads on the descents until 14.4km, then run your race pace, and go all out on the final descent from 39.0km.
  • Start · 0.0km–1.5km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.5km–12.2km · Climb of 786m, descent of 264m averaging 12%. 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 · 12.2km–30.6km · Descent of 257m averaging 12%, climb of 681m, high point 929m. Plus 1 more descent. 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.
  • Fade · 30.6km–39.0km · Climb of 594m. 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 · 39.0km–44.0km · Descent of 640m averaging 13%. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end. Hike the steepest pitches.
