Race strategy

Short race: go all out.

  • Hold your race pace up to the aid station at 5.1km, but stay in control.
  • Control your HR on the first mountain, and go all out on the final descent from 5.1km.
  • Start · 0.0km–1.8km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 1.8km–5.1km · Climb of 503m, high point 1935m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 5.1km–10.2km · Descent of 440m averaging 9%. Kick for the line: give it everything you've got. Long descent: keep it even and let go only near the end.
