Race strategy
Hold a steady pace and save energy for every section.
- 340m descent. Go easy, save your quads.
- Steep 32% wall. Control your pace and stay focused.
- Control your HR on the first mountain, save your quads on the descents until 12.7km, then run your race pace, and go all out on the final descent from 47.1km.
- 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–12.7km · Descent of 340m averaging 19%, descent of 280m averaging 10%. Plus 2 more climbs. 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. Hike the steepest pitches.
- Work · 12.7km–29.8km · Plus 1 more climb and 1 descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
- Fade · 29.8km–47.1km · Climb of 451m, high point 2097m. Plus 1 more climb and 2 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. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
- Home · 47.1km–51.9km · Descent of 351m averaging 7%. No heroics: settle back into your own effort and hold it to the line.
