Race strategy
Hold a steady pace and save energy for every section.
- Steep 41% wall. Control your pace and stay focused.
- 1125m descent. Go easy, save your quads.
- Long race. Control your HR and effort. Early mistakes cost the most.
- Control your HR on the first climb, save your quads on the descents until 65.7km, then run your race pace, and go all out on the final descent from 95.0km.
- Start · 0.0km–1.8km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.8km–12.5km · Plus 1 more climb. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
- Work · 12.5km–52.1km · Descent of 324m averaging 12%. Plus 3 more climbs and 1 descent. 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. Running pays off here: run wherever you can. Hike the steepest pitches.
- Fade · 52.1km–95.0km · Descent of 1125m averaging 8%, high point 896m. Plus 2 more climbs and 1 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. 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. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
- Home · 95.0km–101km · Descent of 460m averaging 7%. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end.
