Col de la Quillane

Col de la Quillane Cycling Climb

The Col de la Quillane sits at a relatively high starting point — 1,255 m — which immediately signals you are already well into the mountains before you turn a pedal on the climb itself. Over 8.3 km it hauls you up 718 m of total ascent to the summit, and the category 2 rating is honest: this is a real climb that demands proper preparation, not a rolling road that happens to trend upward.

What the Numbers Don't Tell You at First Glance

The 5.57% average gradient looks manageable on paper. It is the kind of figure that can lull you into starting too hard. The 23.66% maximum gradient tells a different story. A gap that large between average and maximum means the road is anything but steady — expect sections of genuine ramp that bear no resemblance to the average, interspersed with easier pitches that drag the mean back down.

That spread — nearly 18 percentage points between average and max — is a structural warning. Riders who pace to the average will be caught out when the steep ramps arrive.

How the Ascent Unfolds

Starting at 1,255 m, the climb opens on terrain that is already exposed and can carry wind. The early kilometres tend to offer a false sense of rhythm. Use them to settle breathing and cadence rather than to bank time.

The violent spikes toward that 23.66% maximum are the defining feature of this climb. When the gradient kicks, it kicks hard — the kind of pitch where momentum evaporates in a few pedal strokes if your gearing is wrong or your effort level was already too high. These ramps are not long alpine walls; they are short, brutal interruptions that punish accumulated fatigue.

After the steepest sections ease, the road tends to return to a gradient closer to the average, but the residual lactate from the ramps will still be in your legs. Resist the temptation to push hard on the relief sections — you may need that capacity for another spike ahead.

Pacing Notes

• Do not pace to the average. A 5.57% target effort will leave you under-geared and over-extended the moment a 20%+ ramp appears.
• Identify your threshold before the climb. If you are unsure of your current FTP, use the FTP estimator before building a power target for this ascent.
• Target the steep sections at a repeatable effort, not an explosive one. Spiking to maximum power on each ramp across 8.3 km will accumulate a debt you cannot repay before the summit.
• Gear selection matters more than usual here. The 23.66% maximum is steep enough that running out of gears mid-ramp is a genuine risk. Err on the side of a larger rear cassette than you think you need.

Approach and Context

With only 718 m of total ascent across 8.3 km, the Quillane is not an all-day sufferfest in the way a longer alpine col might be. But the high starting elevation of 1,255 m means any aerobic deficit from altitude is already present before you start, and the jagged gradient profile punishes inefficient effort distribution more than a smoother climb would.

Treat the average gradient as background information. Treat the maximum gradient as the climb's true character.
