Difficulty breakdown: With 5498m of climbing over 154.8km, this HC climb is extremely demanding. The 3.6% average gradient is deceptive: the profile shows plenty of sections above 7-8%, including a brutal finale (KM 146-148: 8-10%). The descents (KM 38-39, 92, 120-137) offer little respite since they're short and followed straight away by more climbing.
Pacing advice:
1. Spin along at endurance pace for the first 20km (≤2% gradient) to save your legs before the first 6-7% ramps.
2. Plan ahead for the hard sections like the KM 22-35 block (6-7%) and the finale, easing off before them so you don't blow up.
3. Make the most of the short descents (e.g. KM 92, 124-126) to recover actively without coasting, but don't back off completely.
