Tips

Difficulty analysis: This 4th category climb is moderately hard. The average gradient of 4% is deceptive: the first half-kilometer at 7% is demanding, followed by more rolling sections (2%). The real challenge is the irregularity, with repeated stretches at 5% (KM 1.0-2.0 and 3.0-3.5) that require constant effort adjustments.

Tips for managing your effort:

1. Start easy: Don't let the steep opening gradient (7%) get the better of you. Keep a controlled pace to save your legs for the 5% sections.

2. Active recovery: Make the most of the 2% parts (KM 0.5-1.0, 2.0-2.5, final) to ease off the pressure slightly and get your breathing back into a steady rhythm.

3. Anticipate the changes: The climb is short but varied. Keep an eye on gradient changes so you can adjust your gear and cadence smoothly, without jerky pedaling.
