Difficulty breakdown: This category 2 climb covers 7.3 km for 355 m of elevation gain, an average gradient of 4.9%, which makes it a demanding but very doable ascent. The steepest sections are between km 1.0 and 1.5 (8%) and between km 2.5 and 4.0 (6 to 7%), where the effort stays sustained without let-up. The stretch from km 4.0 to 5.5, with gradients of 1 to 2%, gives you a real breather before the finale, which ramps back up to 7% between km 6.0 and 6.5.

Tips for managing your effort:

1. Pace the start In the first kilometers, especially between 0.0 and 1.5 with gradients of 6 to 8%, don't go out too hard. Settle into a steady rhythm right from the foot of the climb.

2. Recover on the flat section Use the 4.0 to 5.5 km stretch, at 1 to 2%, to take on fuel, relax your legs and build your cadence back up before the final push.

3. Hold it together to the top Between 5.5 and 7.3 km, keep a smooth cadence and stay seated when you hit the 7% section between 6.0 and 6.5 km so you don't burn out before the summit.
