Col de Malatra

Overview

Col de Malatra is a genuine hors catégorie test, the sort of climb that earns its HC rank through sheer accumulation rather than a single wall. It runs 27.8 km from a valley floor at 612 m all the way up to a summit at 2268 m, stacking up 1656 m of net elevation gain along the way. Total ascent comes in at 1657 m, so the road only rarely gives anything back — this is a climb that points relentlessly upward. The average gradient of 5.96% sounds civilized on paper, but at nearly 28 km long, that steadiness is exactly what makes it dangerous. There is a lot of altitude to gain and a long time in which to gain it.

How the Gradient Unfolds

The headline average of 5.96% masks a road with real variation. With a maximum gradient of 15.32%, there are ramps here more than two and a half times steeper than the mean, and those pitches are where the climb bites. Because total ascent (1657 m) sits only 1 m above the net gain (1656 m), you can trust that almost every metre of road tilts upward — there are no meaningful descents to recover on. Expect the grade to sit near the average for long stretches, then sharpen into steeper pitches that drag you toward that 15.32% ceiling. The climb tops out at 2268 m, high enough that thinner air will quietly tax you in the final kilometres.

Pacing Notes

Over 27.8 km, discipline beats bravado. Anchor your effort to your FTP and aim to hold a sustainable percentage of it rather than chasing the steep ramps. The steadier sections near 5.96% are where you bank time; the pitches toward 15.32% are where you protect your legs by shifting down and spinning rather than grinding. If you don't know your threshold, run the numbers through the FTP estimator before you go, then set a target you can defend for the full hour-plus this climb will demand. Starting at 612 m and finishing at 2268 m means the air keeps thinning — leave headroom for the top.

Gearing

With 1656 m to climb and gradients reaching 15.32%, gearing is not a place to be brave. A compact 34-tooth chainring paired with a wide cassette is the sensible baseline. A 34×32 will get many riders up the sustained 5.96% sections comfortably, but on the steepest ramps toward 15.32% you'll be grateful for one more sprocket — a 34×34 gives you that extra margin to keep cadence high and torque low. Over 27.8 km, the lower gear pays for itself many times over. Choose the easier ratio if you're in any doubt.

Summary

Col de Malatra is a long, honest HC climb: 27.8 km of near-continuous ascent from 612 m to 2268 m, gaining 1656 m at a steady 5.96% with ramps that spike to 15.32%. Pace it by threshold, gear it low, and respect the altitude.
