Race strategy
Run the downhill at race pace, but focus on the climb.
- 620m descent. Go easy, save your quads.
- The finish is runnable. Save your legs to run it all the way.
- Ease into the early runnable section, save your quads on the descents until 14.6km, then run your race pace.
- Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.9km–6.4km · Ease in: hold back more than feels necessary. The race is still ahead. Running pays off here: run wherever you can.
- Work · 6.4km–18.1km · Descent of 620m averaging 8%, climb of 549m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them.
- Home · 18.1km–38.1km · 20.0km of runnable trail, high point 2487m. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
