Race strategy

Start easy, build your effort, and go all out at the finish.

  • Start easy and control your HR up to 17.1km.
  • Hold your race pace up to 20.4km, but stay in control.
  • The finish is runnable. Save your legs to run it all the way.
  • Ease into the early runnable section, then run your race pace.
  • Start · 0.0km–2.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.6km–17.1km · Ease in: hold back more than feels necessary. The race is still ahead. Running pays off here: run wherever you can.
  • Work · 17.1km–20.4km · Climb of 234m, high point 839m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 20.4km–42.0km · 21.6km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
