Difficulty analysis: This 89.3 km climb is a beyond category (HC) ultra-endurance effort. The 5% average gradient is deceptive, because the profile is very uneven. The difficulty lies in the length and the string of steep sections (several km between 7% and 10%, notably between KM 44-52 and 78-80) broken up by short flat stretches or descents that disrupt your rhythm.
Pacing tips:
1. Settle into a steady base pace. Set your effort by the 5% average gradient and hold it, especially in the easier opening km. Avoid overcooking it in the 8-9% sections.
2. Use the descents and flat stretches to recover. KM 8-10, 14-15, 25-28 and 59-61 are crucial opportunities to ease off without killing your momentum, saving your energy.
3. Anticipate the hard sections. Prepare mentally and physically for the long, severe stretches (e.g. KM 44-52). Manage your hydration and nutrition before these demanding passages.
