Difficulty breakdown: At 58.1 km averaging 2.4%, this climb is a pure endurance test. The main challenge is its length and its uneven profile. Although the gradient is mostly moderate (plenty of stretches at 1-3%), several steeper sections (4-5%) between km 18 and km 41 call for extra care.
Pacing advice:
1. Managing your pace over the distance: Resist the urge to go over the top in the first kilometres, which are very flat. Settle into a steady rhythm, a bit below your threshold, to save something for the long haul.
2. Anticipating the gradient changes: The 4-5% sections (e.g. KM 18-20, 35-38, 41-42) demand more from your legs. Get ready for them by shifting into an easier gear early, without blowing up your heart rate.
3. Using the breathers: Make the most of the short descents (KM 19-20) and the 0-1% flat stretches to recover actively: ease off the pressure on the pedals a little while keeping your cadence up.
