Race strategy

Hold a steady pace and save energy for every section.

• 448m descent. Go easy, save your quads.
• Steep 29% 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.
• Ease into the early runnable section, save your quads on the descents until 36.0km, then run your race pace.
• Start · 0.0km–1.8km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.8km–15.6km · 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. Running pays off here: run wherever you can.
• Work · 15.6km–32.4km · Descent of 448m averaging 6%, climb of 789m, high point 1002m. 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. Hike the steepest pitches.
• Fade · 32.4km–42.8km · Descent of 570m averaging 16%. 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. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 42.8km–54.9km · 12.0km 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.
