Race strategy

Short race: go all out.

  • High point at 2647m. Control your HR at altitude.
  • Hold your race pace up to Andesite Mountain, but stay in control.
  • Go easy on the first downhill, then run your race pace, and go all out on the final descent from 7.2km.
  • Start · 0.0km–1.2km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 1.2km–7.2km · Climb of 445m, high point 2647m. Plus 1 more descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. At altitude your pace drops, and that's fine.
  • Home · 7.2km–10.1km · Descent of 353m averaging 12%. Kick for the line: give it everything you've got. At altitude your pace drops, and that's fine.

Summits

Poles

Quad damage

There is too little runnable descent to damage the quads: plan the race around climbing and fuelling.
