Race strategy

Short race: go all out.

  • Hold your race pace up to 8.8km, but stay in control.
  • Control your HR on the first mountain, and go all out on the final descent from 8.8km.
  • Start · 0.0km–2.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 2.7km–8.8km · Climb of 483m, high point 1302m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 8.8km–17.1km · Descent of 448m averaging 5%. Kick for the line: give it everything you've got. Long descent: keep it even and let go only near the end.
