Difficulty breakdown: This Cat 1 climb has a two-stage profile. The first half (KM 0-7) is moderate (gradients of 0 to 4%), a warm-up of sorts. The difficulty ramps up significantly in the second part, with a string of sections at 6%, 7% and even 8% between KM 8 and 14.9. The 4.6% average gradient is misleading; the finale is brutal.
Pacing advice:
1. Manage your pace: Use the first part (gradients under 4%) to settle into a steady rhythm without going into the red. Don't go over the top before KM 8.
2. Prepare for the steep sections: Get ready mentally and physically for the tough stretches (KM 8-9, 9-10, 11-12, 13-14). Keep a smooth, fluid cadence and stay seated to conserve energy.
3. Save something in the tank: The steepest pitch (8%) comes at KM 13. Hold something back so you can maintain your power over the last 2 km.
