Race strategy
Hold a steady pace and save energy for every section.
- 268m 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 19.5km, then run your race pace, and go all out on the final descent from 37.4km.
- Start · 0.0km–2.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 2.1km–15.2km · Descent of 268m 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. Running pays off here: run wherever you can.
- Work · 15.2km–28.2km · Descent of 346m averaging 15%. Plus 2 more climbs. 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.
- Fade · 28.2km–37.4km · Climb of 443m, high point 459m. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. 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 · 37.4km–43.8km · Descent of 459m averaging 7%. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end.
