Race strategy

Hold a steady pace and save energy for every section.

  • 732m descent. Go easy, save your quads.
  • Steep 45% wall. Control your pace and stay focused.
  • Final 846m descent. Save your legs to go all out on it.
  • Control your HR on the first mountain, save your quads on the way down from it until 12.6km, then run your race pace, and go all out on the final descent from 16.4km.
  • Start · 0.0km–2.4km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.4km–12.6km · Climb of 811m, descent of 732m averaging 13%, high point 1049m. 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.
  • Work · 12.6km–16.4km · Plus 2 more climbs and 1 descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
  • Home · 16.4km–21.9km · Descent of 846m averaging 15%. 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.

Poles

Quad damage

Quad damage risk is moderate (index 24 of 100), with 27% of the load in the first half: 1 descent deserves a plan and a couple of downhill sessions before race day.

  • Control your HR on the first mountain, save your quads on the way down from it until 12.6km, then run your race pace, and go all out on the final descent from 16.4km.

  • 16.4–21.8 km · 846 m D−, -15.5% · 0.0 km ahead → even, let go at the end
