Difficulty breakdown: With 8,361m of climbing over 76.1km, this ascent is extremely demanding. The 11% average gradient is misleading: the profile shows big swings, with very steep sections (15% at km 39, 11% at km 29 and 31) broken up by flat or slightly descending stretches. The difficulty comes from the length combined with the uneven gradient, which wrecks your rhythm.
Managing the effort:
1. Hold a steady rhythm by aiming for constant power or heart rate, especially in the first kilometres (2-4% gradients), so you don't blow up early.
2. Anticipate the gradient changes using the kilometre-by-kilometre profile: ease off before the brutal ramps (e.g. km 39 at 15%) and make the most of the 0-2% sections to recover by spinning easy.
3. Manage your hydration and nutrition over the long haul: plan strategic stops on the flatter parts (e.g. km 49-52) to keep your energy stores topped up on a climb that takes several hours.
