Race strategy
Run easy on the first mountain, then go all out on the second.
- 342m descent. Go easy, save your quads.
- Final 711m descent. Save your legs to go all out on it.
- Steep 32% wall. Control your pace and stay focused.
- Control your HR on the first mountain, save your quads on the way down from it until 9.8km, then run your race pace, and start the final descent from 15.0km under control, then go all out near the bottom.
- Start · 0.0km–1.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.1km–6.0km · 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.
- Work · 6.0km–15.0km · Descent of 342m averaging 9%, climb of 572m, high point 530m. 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.
- Home · 15.0km–25.2km · Descent of 711m averaging 7%. 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. Hike the steepest pitches.
