Difficulty breakdown: This 67.2 km climb is an extreme test of endurance. The 5.8% average gradient is misleading, because the profile shows some big variations. The real difficulty lies in the length and in the concentration of the steepest pitches (9% to 16%) in the second half, especially between km 43 and km 63, with very hard sections such as km 45-46 at 16%.
Tips for managing the effort:
1. Pacing: Start very easy over the first kilometres (gradients of 1-6%) to save your legs. Save your main effort for the middle and final sections, which are much steeper.
2. Anticipate the key sections: Mentally identify the critical stretches (e.g. km 45-55 with gradients above 10%) so you can adjust your effort and your gear in advance, before you're in trouble.
3. Hydration and fueling: Given the estimated climbing time (probably 3 to 5 hours), plan your water and carb intake carefully to avoid bonking and dehydration over such a long effort.
