Col de Malval

Overview

The Col de Malval is a Category 2 climb in France, running 8.1 km from base to summit. It starts at 336 m and tops out at 747 m, giving a net elevation gain of 411 m. On paper that reads as a steady mid-length effort, and the 5.1% average gradient supports that impression — long enough to demand a plan, short enough to hold a real effort throughout.

But the net figure understates the work. Total ascent is 549 m against a net gain of just 411 m, a difference of 138 m. That gap means the road undulates: you climb, give some elevation back, then climb again. Those 138 extra metres are hauled over ground you also have to descend, so the true energetic cost is higher than the net gain suggests. Expect an effort that never fully settles into one rhythm.

How the Gradient Unfolds

A 5.1% average tells you almost nothing about how this climb actually feels. The undulation means the real gradient swings well above and below that number, and the steepest ramp bites hard: the maximum pitch reaches 14.63%, nearly three times the average. Plan for the number on the sign to be a poor guide to the road under your wheels.

• Flatter and slight-descent sections where you recover but also carry speed
• Repeated short climbs stacked back to back, each resetting your legs
• A single steepest ramp near 14.63% that forces you out of your seated rhythm

Pacing Notes

On an undulating climb like this, chasing an even speed is a trap — you overspend on every rise and coast the dips. Instead, pace by even effort. Hold a steady sustainable power output through the ramps and let your speed rise on the flatter and downhill sections rather than pushing to keep the pace constant.

Over the 138 m of hidden ascent, small pacing errors compound fast. If you don't know your ceiling, run the numbers through the FTP estimator first, then ride the steep pitches just under threshold and use the recovery sections to actually recover.

Gearing

The 14.63% maximum ramp governs your gearing choice, not the 5.1% average. Turn up under-geared and you'll be grinding at low cadence exactly where the road is steepest. Run a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you a bailout gear that keeps your cadence up on that steepest pitch. Check your setup before the ride; a cassette swap is a garage job, not a roadside one.

Summary

• Length: 8.1 km
• Average gradient: 5.1%
• Maximum gradient: 14.63%
• Net elevation gain: 411 m
• Total ascent: 549 m
• Category: 2

The Col de Malval rewards riders who respect its undulation. Pace by effort, gear for the 14.63% ramp, and treat the 549 m of total ascent — not the 411 m net — as the real measure of the day.
