Race strategy

Hold a steady pace and save energy for every section.

• 543m descent. Go easy, save your quads.
• 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 39.1km, then run your race pace.
• Start · 0.0km–1.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.7km–16.3km · Plus 2 more climbs and 1 descent. 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 · 16.3km–63.7km · Climb of 621m, high point 1016m, descent of 543m averaging 17%, descent of 546m 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. Running pays off here: run wherever you can.
• Fade · 63.7km–65.9km · Plus 1 more descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 65.9km–108km · 41.6km 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.

The longest climb runs 7.7km at an average 8.1% grade (621m of vertical). The longest descent runs 9.5km at an average 5.7% grade (546m of vertical). The steepest climb averages 24.4% over 0.6km. The steepest descent drops at 27.8% over 0.3km. Surface: 47% trail, 23% smooth, 22% road, and 7% technical. Flat-equivalent effort: 139.6 FlatKM.

Poles

Poles bring little benefit here: only about 10.9km of pole-friendly terrain.

Quad damage

Quad damage risk is moderate (index 43 of 100), with 57% of the load in the first half: 2 descents deserve a plan and a couple of downhill sessions before race day.

• Control your HR on the first mountain, save your quads on the descents until 39.1km, then run your race pace.
• #1 · 24.0–27.2 km · 543 m D−, -16.9% · 80.4 km ahead → control
• #2 · 29.6–39.1 km · 546 m D−, -5.7% · 68.4 km ahead → control
