Race strategy
Hold a steady pace and save energy for every section.
- 553m 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.
- Control your HR on the first mountain, save your quads on the descents until 59.3km, then run your race pace.
- Start · 0.0km–1.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.1km–12.8km · Climb of 531m, descent of 553m averaging 7%. 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.
- Work · 12.8km–52.8km · Descent of 366m averaging 14%, descent of 789m averaging 14%, descent of 473m averaging 8%. Plus 4 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.
- Fade · 52.8km–91.1km · Descent of 694m averaging 11%, climb of 922m, climb of 742m, high point 1192m. Plus 2 more 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. 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 · 91.1km–99.5km · 8.3km 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.
