Col du Noyer

What to Expect on the Col du Noyer

The Col du Noyer sits in the Category 1 bracket, and it earns that classification honestly — not through sheer length or relentless gradient, but through the combination of a sustained 12.1 km effort and sections that will detonate poorly paced legs without warning. Starting at 950 m elevation, the road climbs 719 m net to the summit at 1,669 m, though the total ascent of 910 m tells you something important: this is not a clean, linear grind. There are undulations, short descents, and recoveries baked into the profile that inflate real climbing work well above the net figure.

Gradient Profile: Averages Lie

The headline average of 5.95% sounds manageable — and for much of the lower and mid-sections, it is. Expect stretches of moderate climbing in the 5–8% range where you can settle into a rhythm, manage heart rate, and conserve glycogen. Do not mistake these passages for permission to push hard.

The maximum gradient of 33.63% is the number that demands respect. A pitch of that severity is not a ramp — it is closer to a wall. Ramps of this gradient appear abruptly in Alpine terrain and can last long enough to force riders out of any sustainable power zone and into pure survival mode if they arrive with depleted legs. The total ascent figure of 910 m versus the net gain of 719 m confirms there are sections where gradient spikes are followed by brief relief, which can lull you into accelerating before the next steep pitch.

Pacing Strategy

• Bottom third: Resist the temptation to use the moderate early gradient to set a tempo you cannot sustain. The climb is 12.1 km long; the first few kilometres should feel almost too easy.
• Middle section: This is where many riders drift above threshold chasing a group or responding to a false flat. Keep effort controlled relative to your FTP. If you don't have a current FTP figure, use the FTP estimator before your target day.
• Approach to steep pitches: When gradient kicks above roughly 15%, shift early — do not wait until you are grinding to a halt. Cadence drops sharply on walls like this, and a forced gear change under load risks a chain drop or a complete stall.
• The maximum gradient sections: At gradients approaching 33%, even riders with low-ratio gearing will be at or near their physical ceiling. If you have a compact chainset, make sure the rear cassette runs to at least 32T or larger. Riders on standard gearing should plan to be already in their lowest combination well before the gradient peaks.

Gearing Considerations

For a climb with a maximum gradient exceeding 33%, standard road gearing (50/34 front, 11-28 rear) is marginal at best for most riders. A 32T or 34T rear sprocket is strongly advisable. Gravel bikes with wide-range drivetrains will handle the extreme pitches with less distress, though the 12.1 km total length and 910 m of total climbing means gearing decisions affect the entire effort, not just the hardest moments.

The Bigger Picture

The Col du Noyer rewards patience and punishes ambition deployed too early. Its 5.95% average is genuinely moderate for an Alpine Cat 1, but that figure masks the variance that defines this climb's character. Treat the comfortable sections as recovery, not as an invitation to accelerate, and arrive at the sharp gradients with legs that still have something to give.
