Difficulty analysis: With 2303 m of elevation gain over 31.8 km, this hors catégorie climb is a demanding endurance test. The average gradient of 7.2% is notable, but the real difficulty lies in the irregular profile: long sections at 9% (KM 18-23) alternate with flat or low-gradient stretches (KM 2-3, KM 10-11), which disrupts your rhythm.
Pacing advice:
1. Hold a steady rhythm by targeting a constant power or heart rate, especially in the first kilometres where the gradient is gentler, so you don't blow up early.
2. Prepare for the key sections: KM 18 to 23 (9% over 5 km) is where the climb really bites. Ease off slightly before this section and use the less steep stretch (KM 24-26) to recover.
3. Manage your hydration and feeding on the low-gradient sections (KM 10-11, KM 24-26) where the effort is lighter, so you don't have to interrupt your rhythm on the steep ramps.
