Difficulty breakdown: This 14.9 km HC climb is a sustained but steady effort. The 5.8% average gradient is typical for a long col, but the kilometre-by-kilometre profile shows no real ramps. The difficulty comes from the length and the constant effort, with a steeper section between km 6 and 10 (6-7% gradients).
How to manage the effort:
1. Pacing: Settle into a steady rhythm from the bottom, matched to the 5.8% average. Don't surge in the first kilometres, which are easier.
2. Prepare for the middle section: Get your head and legs ready for the hardest stretch (KM 6-10, gradients around 7%) and keep something in reserve.
3. Gearing: Choose a gear that lets you hold a steady cadence of around 70-80 rpm, especially on the 6-7% sections.
