Alto de la Cobertoria

Overview

Alto de la Cobertoria is a Category 1 climb in Spain, running 8.2 km from a start elevation of 394 m to a summit at 1,175 m. That gives a net elevation gain of 781 m at an average gradient of 9.48% — a steep, sustained ask that sits firmly in hard-day territory rather than a warm-up.

The headline number to watch is the gap between the net gain of 781 m and the total ascent of 979 m. Those extra 198 m of climbing come from dips and false flats along the way, meaning the road gives back altitude you then have to re-earn. In practice you are climbing roughly a quarter more vertical than the point-to-point figure suggests, and every metre lost is a metre you pay for twice.

How the Gradient Unfolds

A 9.48% average on a road this length is unforgiving, but the average hides how the effort is distributed. Some sections dip toward recovery gradients, which means the steep pitches are steeper than the mean to compensate — including a maximum ramp of 24.1%.

• Flatter or descending sections where the road briefly eases and gives back a little of your 781 m net gain
• Repeated short climbs stacked back-to-back, which is where the extra 198 m of total ascent accumulates
• The steepest ramp at 24.1%, a wall that will spike your effort well above threshold

Pacing Notes

On a smooth climb you can hold near-constant power. Cobertoria's undulation makes that harder: chasing even speed over the dips and the 24.1% ramp will send your power surging and torch your legs early. Aim instead for even effort, letting speed rise on the shallower sections and accepting a slower crawl on the steep pitches. Anchor your pacing to your sustainable power output rather than the number on the screen, and let the ramps run hot only briefly. If you do not know that ceiling, run the FTP estimator before you commit to a target for the day.

Gearing

The steepest gradient governs your gearing choice, and 24.1% demands the widest range you can fit. A compact or sub-compact chainset paired with a wide-range cassette — think 34×32 or 34×34 — gives you a bailout gear that keeps your cadence turning on the wall without cross-chaining or grinding to a stall. Check your actual setup before the ride; discovering you are over-geared halfway up a 24.1% pitch is not a mistake you can pedal out of.

Summary

• Length: 8.2 km
• Average gradient: 9.48%
• Maximum gradient: 24.1%
• Net elevation gain: 781 m
• Total ascent: 979 m
• Category: 1

Alto de la Cobertoria is a short but brutally steep Category 1 test, and its undulation makes it harder than the net gain implies. Pace to effort, gear for the steepest ramp, and respect the 198 m of climbing that the point-to-point figure quietly leaves out.
