Difficulty analysis: This HC climb is genuinely hard because of its uneven profile. The main difficulty lies in three very steep sections (12% at KM1-2, 13% at KM4-5 and 9% at KM9-10) that demand serious efforts. KM5-7 gives you a short breather, with flat then slightly downhill gradient, which is crucial for recovery.
How to manage the effort:
1. Handling the "bumps": Anticipate the three sections above 9%. Drop into an easy gear as you approach them to hold a steady cadence and avoid blowing up.
2. Make the most of the flat: Use the 0% kilometre (KM5-6) to recover actively: ease off the pedals, drink, and get your breathing and rhythm back before what comes next.
3. Pace the finish: The last 3 kilometres are consistently steep (8%). Don't go out too hard after the breather. Find a steady rhythm you can hold all the way to the summit.
