Difficulty breakdown: At 26.6 km averaging 8%, Guadualito is a seriously punishing hors catégorie climb. What makes it so hard is the length combined with steep sections, notably a km at 12% (KM 7-8) and a brutal finish at 15% over the last 600 metres.
How to manage the effort:
1. Pace yourself from the bottom: The first half is more uneven, with frequent 9-12% pitches. Don't go too hard in the opening percents, or you'll burn your legs before the real climbing starts.
2. Save something for the two key sections: Keep some energy in the tank for the km at 12% (around 7-8 km) and, above all, for the final 15% ramp that crowns the climb.
3. Make the most of the recovery sections: Km 21 to 25 offer gentler gradients (3-5%). Use them to recover by keeping the pedals turning before the final push.
