Tips

Difficulty breakdown: This beyond category (HC) climb is genuinely hard, with a demanding average gradient of 7.8% over 10.2 km. Two key sections make it harder: a 9% kilometer (between 5-6 km) and, above all, a very steep 10% kilometer (between 7-8 km), which comes after more than two-thirds of the effort. The 3% kilometer (8-9 km) gives you a welcome breather before a final section at 7%.

Tips for the effort:

1. Manage your pace before the hard part: Ride the first kilometers (6-8%) at a steady pace, without overestimating your legs, so you don't pile up fatigue before the critical sections.

2. Prepare for the 10% kilometer: Ease off a little on the 9% kilometer (5-6 km) to get ready for the next steep ramp (7-8 km). Keep some gears in reserve for that section.

3. Make the most of the breather: Use the 3% kilometer (8-9 km) to recover actively (spin the legs easy) and tackle the final 7% climb with fresh legs.
