Race strategy
Hold a steady pace and save energy for every section.
- 894m descent. Go easy, save your quads.
- Steep 29% wall. Control your pace and stay focused.
- 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 49.8km, then run your race pace, and go all out on the final descent from 91.9km.
- Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.3km–13.2km · Climb of 702m, high point 985m. 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 · 13.2km–49.8km · Descent of 429m averaging 16%, descent of 372m averaging 8%, descent of 894m averaging 7%. Plus 2 more climbs. 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 · 49.8km–91.9km · Plus 3 more climbs and 2 descents. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. 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 · 91.9km–99.1km · Descent of 466m averaging 6%. 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.
