Race strategy
Hold a steady pace and save energy for every section.
- 325m descent. Go easy, save your quads.
- Steep 25% wall. Control your pace and stay focused.
- Control your HR on the first mountain, save your quads on the way down from it until 9.4km, then run your race pace, and go all out on the final descent from 19.4km.
- Start · 0.0km–1.4km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.4km–14.0km · Descent of 325m averaging 10%, high point 323m. 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 · 14.0km–19.4km · 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.
- Home · 19.4km–25.6km · Descent of 295m averaging 5%. No heroics: settle back into your own effort and hold it to the line.
