Difficulty breakdown: This 18.1 km HC climb is a sustained effort with a brutal average gradient of 9%. The difficulty lies in the relentless consistency of the gradients, mostly between 8% and 11%, apart from one 2% breather between KM 12 and 13. With no flat sections at all, it's a constant, demanding grind.
Tips for managing the effort:
1. Pacing: Don't go out too hard on the first kilometres at 10-11%. Settle into a smooth cadence with a gear you can hold for the whole climb.
2. Make the most of the breather: The 2% kilometre (KM 12-13) is a crucial chance to recover, bring your heart rate down and get ready for the final section, which is just as hard.
3. Save something for the finish: The last part (KM 13 to 17) goes back to 9-10% gradients. Keep some mental and physical reserves so you don't blow up over those four decisive kilometres before the gradient eases slightly on the final kilometre.
