Race strategy
Hold a steady pace and save energy for every section.
- 1129m descent. Go easy, save your quads.
- Steep 39% wall. Control your pace and stay focused.
- Final 655m descent. Save your legs to go all out on it.
- 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 83.8km, then run your race pace, and start the final descent from 120km under control, then go all out near the bottom.
- Start · 0.0km–1.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.7km–11.4km · Climb of 643m, descent of 600m averaging 18%. 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 · 11.4km–74.6km · Climb of 1121m, descent of 1129m averaging 20%, descent of 270m averaging 11%. Plus 1 more climb. 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. Running pays off here: run wherever you can. Hike the steepest pitches.
- Fade · 74.6km–120km · Climb of 657m, descent of 868m averaging 13%, climb of 1284m, high point 1958m. 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. 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 · 120km–128km · Descent of 655m averaging 8%. No heroics: settle back into your own effort and hold it to the line. Very long descent: first half under control, then even, let go only near the end.
