Difficulty analysis: This HC climb is genuinely tough because of its length (15.4 km) and its considerable elevation gain (1083 m). The average gradient of 7% is sustained, but the distribution makes the difficulty uneven. The 7% and 8% sections (KM 2-3, 6-7, 8-9, 14-15) are tough, especially the last kilometre at 8%. KM 7-8 at 0% and KM 3-4 at 2% offer brief respite, but the finish stays hard.
Tips for managing the effort:
1. Pace yourself over the first few kilometres: The start is relatively "gentle" (5-6%). Don't go out too hard, so you save something for the steeper ramps that follow.
2. Use the flat bits to recover: Take advantage of the flat section (KM 7-8) and the easier gradients (KM 3-4, 5-6, 9-10) to ease off slightly, drink and eat without losing your rhythm.
3. Save some legs for the finale: Prepare for the last section (KM 14-15) at 8%. Manage your effort over kilometres 10 to 14 (steady 5% gradient) so you tackle that tough final stretch with enough in the tank.
