Difficulty breakdown: This 3 km climb with 167 m of elevation gain averages 5.6% and is rated Category 3. There are no truly brutal sections, but the gradient stays steady and nearly constant the whole way up, with a peak of 7% between km 0.5 and 1.0. The opening stretch at 3% over the first 500 meters gives you a welcome breather before the effort really kicks in. The main challenge is pacing over the duration rather than raw power.
Tips for managing your effort:
1. Don't go out too hard. Use the KM 0.0-0.5 section at 3% to find a steady rhythm and save some legs for later.
2. Prepare for the 7% ramp. Shift to an easier gear before KM 0.5-1.0 and keep a smooth cadence so you don't blow up.
3. Hold your rhythm to the top. On the KM 1.5-2.0 and KM 2.5-3.0 sections, both at 5%, keep a steady effort, then pick it up a little over the final kilometer.
