Difficulty breakdown: Tuil Pass from Kujang-ni is a demanding Category 2 climb: 4.6 km at an average gradient of 5.3% with 246 m of elevation gain, so you're working hard from the bottom to the top. The toughest section is between km 3.5 and km 4.0, at 7%, followed by several stretches at 6% (km 1.5-2.0, km 3.0-3.5 and km 4.0-4.5). The first kilometre, at 4% or 5%, looks more manageable, but it's the consistency of the gradients that makes this climb hard. The final section (km 4.5-4.6) is a short bit at -2% that gives you a little breather before the line.
Tips for pacing the climb:
1. Pace your start. The first 500 metres at 5% tempt you to go out too hard; settle into a steady rhythm so you've got something left for later.
2. Prepare for the 7% section. Between km 3.5 and km 4.0, drop into an easier gear, stay seated if you can, and keep a steady cadence.
3. Manage your hydration and the finish. Drink regularly from km 1.0 onwards, and save some legs for the 6% stretch between km 4.0 and km 4.5, without easing off before the descending false flat.
