Difficulty analysis: This 14.5 km climb is unusual. Although rated hors catégorie, its average gradient of 4.2% is moderate. The difficulty lies in how it's broken up: a demanding opening section (KM 2-4 at 8-9%) is followed by a long 5 km stretch that is either gently descending or flat, where you have to back right off. The final section (KM 12-13 at 7%) means picking the effort back up after that lull, which is both mentally and physically tricky.
Tips for managing your effort:
1. Pacing: Don't go too hard in the first 4 kilometers. Save something for the final 7% section. The central descent (KM 4-9) is your chance to recover actively without losing momentum.
2. Anticipating gradient changes: Be mentally ready for the abrupt transitions, especially the ramp back up after the long descent. Get into an easier gear before the KM 12 ramp.
3. Varying your effort: Hold a steady power output on the steep sections, make the most of the flat parts to spin your legs easily, and use the descents to recover your muscles while keeping the pedals turning.
