Tips

Difficulty breakdown: With 2,817m of climbing over 42km, this hors catégorie ascent is a real test of endurance. The 6.7% average gradient is demanding, but the real challenge is how inconsistent it is. There's a very steep section at 11% (km 20-21), and several flat stretches or slight descents (km 25-26, 31-33, 36-37) that break your rhythm.

Pacing tips:

1. Manage the changes in gradient: Anticipate the shifts in gradient. Use the flat or downhill sections (like between km 25 and 33) to recover by spinning smoothly without stopping.

2. Run an easier gear: The length of the climb and the 8-11% kicks call for proper gearing to keep a steady cadence (>70 rpm) and avoid premature muscle fatigue.

3. Break the climb into sections: Split it up based on the changes in gradient. Focus on one section at a time to manage your effort mentally over such a long distance.
