Analysis of the difficulty:
This climb is a major challenge. An average gradient of 10.2% over 6.6 km makes it a legitimate hors catégorie climb. The difficulty lies in the consistency of the steep gradients, with five sections at 13% or 14%, and only two kilometres of "recovery" at 5% between km 5.0 and km 6.0.
Tips for managing the effort:
1. Pace yourself from the bottom: The first kilometres are very steep (9% to 14%). Don't go out too hard or you'll blow up before the slightly easier section.
2. Make the most of the reprieve: The section between 5.0 and 6.0 km (5% gradient) is crucial. Use it to recover while keeping a good rhythm before the final push at 10%.
3. Choose your gearing wisely: The consistency of gradients above 10% calls for the right gearing. Run a compact ratio to keep a steady cadence without burning out your legs too early.
