Race strategy

Short race: go all out.

  • Hold your race pace up to Sabotino / Sabotin, but stay in control.
  • Control your HR on the first mountain, and go all out on the final descent from 5.2km.
  • Start · 0.0km–2.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 2.6km–5.2km · Climb of 555m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 5.2km–9.9km · Descent of 517m averaging 11%, high point 585m. Kick for the line: give it everything you've got. Long descent: keep it even and let go only near the end.

Quad damage
