Difficulty analysis: This 16.6 km HC climb is genuinely hard, with an average gradient of 7%. The difficulty is uneven: the first third is relatively mild, but the heart of the climb (km 9 to 11) is very demanding, with gradients of 10% and 11%. A short, slightly downhill false flat at km 11 gives you a brief respite before a sustained finish (8 to 9% gradients from km 12 to 15).
Tips for managing your effort:
1. Pace yourself: Start easy on the first kilometres, which are less steep, to save your legs for the critical sections.
2. Anticipate the changes of rhythm: Get ready mentally and physically for the steep ramps between km 9 and 11. Use the slight false flat at km 11 to recover without losing your rhythm.
3. Save something for the end: Even though the gradient eases over the last half kilometre, the final four kilometres are still tough (7% to 9%). Don't empty the tank too early.
