Race strategy

Hold a steady pace and save energy for every section.

• 628m descent. Go easy, save your quads.
• Big early climb with 1.4km gain. Hold your pace, save your legs for later.
• Final 1590m 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 way down from it until 14.8km, then run your race pace, and start the final descent from 87.8km 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–14.8km · Climb of 668m, descent of 628m averaging 10%. 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. Hike the steepest pitches.
• Work · 14.8km–57.4km · Climb of 1435m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
• Fade · 57.4km–87.8km · Descent of 512m averaging 7%, high point 1811m. Plus 3 more climbs. 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 · 87.8km–105km · Descent of 1590m averaging 9%. 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.

Course

By gradient, 33% of the distance is uphill, 36% downhill and 31% flat. The longest climb runs 12.2km at an average 11.7% grade (1435m of vertical). The longest descent runs 17.3km at an average 9.2% grade (1590m of vertical). The steepest climb averages 29.6% over 0.4km. The steepest descent drops at 36.9% over 0.2km. Surface: 37% trail, 29% road, and 18% smooth. Flat-equivalent effort: 144.1 FlatKM.

Poles

Trekking poles are worth taking: about 11.6km of the course favours them.

Quad damage

Quad damage risk is high (index 50 of 100), with 30% of the load in the first half: 1 critical descent. Downhill-specific preparation and a controlled early pace pay off here.

• Control your HR on the first mountain, save your quads on the way down from it until 14.8km, then run your race pace, and start the final descent from 87.8km under control, then go all out near the bottom.
• #1 · 8.4–14.8 km · 628 m D−, -9.8% · 90.2 km ahead → control
• 77.6–84.6 km · 512 m D−, -7.3% · 20.4 km ahead → your pace
• 87.8–105.1 km · 1590 m D−, -9.2% · 0.0 km ahead → even, first half under control, let go at the end

Weather

On race day, start temperatures have historically ranged from 22°C to 33°C, with around 11°C at the highest point; the chance of precipitation is about 50%.
