Race strategy

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

• 296m descent. Go easy, save your quads.
• Steep 39% wall. Control your pace and stay focused.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Ease into the early runnable section, save your quads on the descents until 14.8km, then run your race pace.
• 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–54.6km · 11.6km of runnable trail, high point 1070m, descent of 296m averaging 9%. 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. Running pays off here: run wherever you can. Hike the steepest pitches.
• Fade · 54.6km–86.1km · Plus 1 more descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Running pays off here: run wherever you can. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 86.1km–99.5km · Climb of 1100m. No heroics: settle back into your own effort and hold it to the line. Climb by heart rate or breathing, not pace.
