Difficulty breakdown: This 8 km climb has two distinct phases. The first 2 km are relatively easy, with gradients of 2-3%, and serve as a warm-up. The real difficulty kicks in abruptly at KM 2.0 with a tough 4 km section where the gradient stays consistently above 8%, peaking at 12% between KM 2.0-2.5 and 3.5-4.0. This steep central part accounts for most of the climbing and gives the climb its Cat 1 character. The final 2 km offer a welcome break, with gradients easing from 4% to 2%.
Tips for managing the effort:
1. Pacing: Use the first 2 km to find your rhythm without burning matches. Expect the hard part from KM 2.0 onward, and adjust your effort to keep a steady cadence on the sections at 10-12%.
2. Mental approach: Break the climb into three sections: the approach (KM 0-2), the hard core (KM 2-6) and the run-in to the top (KM 6-8). Focus on getting through the central section one kilometre at a time.
3. Energy management: On the steepest pitches, spin a light gear to avoid blowing up. Use the final kilometres, which are less steep, to recover a bit and push the pace if you have anything left in the tank.
