Col de Xatard
A 12.2 km Cat 3 climb in France with a deceptively mild 3.22% average gradient — but a savage 18.18% maximum punch hidden somewhere in the profile.

The climb
Gradient profile
Overview
Col de Xatard sits in the Category 3 bracket, but the headline average of 3.22% over 12.2 km understates how this road actually rides. The net elevation gain is 392 m, but the total ascent logged across the full profile is 786 m — almost exactly double. That gap tells you everything: the road is not a steady ramp. It rolls, dips, and then bites hard, meaning your legs accumulate far more work than the net number suggests.
How the Gradient Unfolds
With an average gradient of 3.22%, large sections of Col de Xatard will feel manageable, even comfortable. Treat those sections with respect — they are not rest, they are opportunity. The climb's maximum gradient of 18.18% is severe by any standard. A ramp at that pitch demands either a very low gear or a significant burst of power, and arriving at it with pre-fatigued legs from burning unnecessary matches on the flatter kilometres is the most common mistake here.
The difference between the 392 m net gain and 786 m total ascent confirms there are meaningful descents or flat recoveries woven into the 12.2 km. Use them deliberately. Spin out, recover breathing, and lower your heart rate before the road tilts upward again.
Pacing Notes
- Don't chase the false flat sections. The mild average gradient invites riders to push well above their FTP on the easier pitches. Resist. The 18.18% maximum wall will expose any early aggression.
- Treat this as an uneven effort, not a steady-state climb. Variable terrain like this suits a power-based approach: target a ceiling on the gradual sections and accept that you'll spike briefly on the steepest ramp rather than trying to ride it at the same watts.
- The rolling profile rewards mental patience. Every time the road eases or drops, the temptation is to accelerate. Keep cadence up, keep power controlled.
Gearing Recommendations
The 18.18% maximum gradient is the governing factor for gearing selection. On a climb where most of the road feels moderate, riders frequently arrive at the steepest section in a gear that's too big to spin comfortably.
- Road bikes: A compact chainset (50/34) with at least an 11-32 cassette is advisable. An 11-34 gives more comfort on the maximum pitch, particularly if the steep section is sustained rather than a single sharp kick.
- Gravel or endurance bikes: Standard gravel gearing handles this climb with ease.
- Check your setup before you start using the FTP estimator to model what the steepest sections will demand relative to your current fitness.

Bottom Line
Col de Xatard is a climb that flatters to deceive. The Category 3 rating and sub-4% average make it look straightforward on paper. The near-18% maximum and the rolling profile that doubles the total ascent relative to net gain make it considerably harder in practice. Ride conservatively on the easy ground, gear appropriately for the sharp stuff, and treat the descents and flats as genuine recovery windows rather than acceleration zones.
