Race strategy
Hold a steady pace and save energy for every section.
- Big early climb with 1.1km gain. Hold your pace, save your legs for later.
- 389m descent. Go easy, save your quads.
- Final 1404m descent. Save your legs to go all out on it.
- Long race. Control your HR and effort. Early mistakes cost the most.
- Control your HR on the first mountain, save your quads on the descents until 25.9km, then run your race pace, and start the final descent from 36.3km under control, then go all out near the bottom.
- Start · 0.0km–1.5km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.5km–10.3km · Climb of 1069m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
- Work · 10.3km–25.9km · Descent of 389m averaging 7%, descent of 313m averaging 6%. Plus 1 more climb. 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.
- Fade · 25.9km–36.3km · Climb of 522m, climb of 263m, high point 1541m. Plus 1 more descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
- Home · 36.3km–54.3km · Descent of 1404m averaging 8%. No heroics: settle back into your own effort and hold it to the line. Very long descent: first half under control, then even, let go only near the end. Hike the steepest pitches.

Quad damage
