Race strategy

Run the downhill at race pace, but focus on the climb.

• 491m descent. Go easy, save your quads.
• Steep 27% wall. Control your pace and stay focused.
• The finish is runnable. Save your legs to run it all the way.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Ease into the early runnable section, save your quads on the descents until 35.5km, then run your race pace.
• Start · 0.0km–1.2km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.2km–29.8km · Descent of 491m averaging 15%, climb of 722m, high point 756m. Ease in: hold back more than feels necessary. The race is still ahead. 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. Running pays off here: run wherever you can.
• Fade · 29.8km–35.5km · Descent of 786m averaging 14%. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. This descent is hard on the legs: short steps, stay in control, poles if you have them. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 35.5km–52.0km · 16.5km 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.

Quad damage

Quad damage risk is moderate (index 31 of 100), with 45% of the load in the first half: 2 descents deserve a plan and a couple of downhill sessions before race day.

• Ease into the early runnable section, save your quads on the descents until 35.5km, then run your race pace.
