Race strategy

Run the climb at race pace, build your speed on the downhill, and go all out at the finish.

  • Final 1055m descent. Save your legs to go all out on it.
  • Steep 28% wall. Control your pace and stay focused.
  • Control your HR on the first mountain, and go all out on the final descent from 16.1km.
  • 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–16.1km · Climb of 1338m, high point 2364m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
  • Home · 16.1km–23.9km · Descent of 1055m averaging 14%. Build to the finish: leave whatever you have left out on the course. Long descent: keep it even and let go only near the end. Hike the steepest pitches.

Course

The course climbs 1350m+. With 54m/km of climbing, this is a true mountain course with sustained climbs and descents. By gradient, 52% of the distance is uphill, 36% downhill and 13% flat.

Poles
