Race strategy
Hold a steady pace and save energy for every section.
- 898m 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.
- Control your HR on the first mountain, save your quads on the descents until 118km, then run your race pace.
- Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.3km–9.9km · Descent of 328m averaging 10%. 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 · 9.9km–87.0km · Descent of 516m averaging 9%, descent of 619m averaging 9%, descent of 898m averaging 6%. Plus 6 more climbs and 3 descents. 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 · 87.0km–163km · Descent of 734m averaging 8%. Plus 3 more climbs and 4 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. 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 · 163km–170km · 6.7km 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.
