Col de Soubeyrand

Overview

Col de Soubeyrand is a Category 2 climb in France, running 10.6 km from a start elevation of 425 m to a summit at 979 m. Across that distance it delivers a net elevation gain of 554 m at an average gradient of 5.22%. On paper that average reads as moderate, the kind of number that suggests a steady tempo effort you can settle into and hold.

The paper number lies. Total ascent over the climb is 820 m, which is 266 m more than the net gain. That gap tells you the road undulates: it gives back altitude in dips and false flats, then makes you re-earn it. Every metre you coast down is a metre you have to climb again, so the true climbing load is closer to 820 m than 554 m. Plan your effort around the harder figure.

How the Gradient Unfolds

A 5.22% average is a blend, not a description. Because the road sheds and regains 266 m of elevation, some sections are near-flat or downhill while others are considerably steeper than the mean to compensate. Expect the gradient to swing rather than hold.

• Flatter and recovery sections where the road levels or tips downhill, letting you soft-pedal
• Repeated short climbs that follow each dip, each one steeper than the average
• A steepest ramp that spikes well into double digits, far above the 5.22% mean

Read the road ahead and stay off the gas on the flat parts so you have something left for the ramps.

Pacing Notes

On an undulating climb like this, even-effort and even-speed pacing pull in opposite directions. Chasing an even speed forces you to surge on every ramp and bleed matches you cannot recover on the descents. Pacing to an even effort, holding a steady sustainable power output, keeps your metabolic cost flat while your speed naturally rises and falls with the terrain.

Anchor your target to a percentage of threshold and let the ramps push you briefly above it, the flats pull you below. If you do not know your number, run the FTP estimator before you go so your ceiling is grounded in data rather than feel.

Gearing

The steepest ramp is what dictates your gearing, not the average. When pitches climb into the high teens, a standard chainset will leave you grinding at unsustainable cadence. Fit a compact or sub-compact chainset paired with a wide-range cassette, a 34×32 or 34×34 combination, so you can spin the steep sections rather than muscle them. Confirm your chainrings and cassette before the ride, not at the base of the first ramp.

Summary

• Length: 10.6 km
• Average gradient: 5.22%
• Net elevation gain: 554 m
• Total ascent: 820 m
• Category: 2

Col de Soubeyrand rewards riders who respect the gap between its gentle average and its real demands. Pace to effort, gear for the steepest ramp, and treat the full 820 m of ascent as the work ahead.
