Race strategy

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

  • Final 641m descent. Save your legs to go all out on it.
  • Steep 26% wall. Control your pace and stay focused.
  • Control your HR on the first mountain, and go all out on the final descent from 8.6km.
  • 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–8.6km · Climb of 783m, high point 871m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
  • Home · 8.6km–13.6km · Descent of 641m averaging 13%. 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.
